Managing nature in a community-friendly way

ZZ2 is managed as a living, open system and aims to create value for all its stakeholders. Nowhere is this more evident than in this farming enterprise’s attitude towards nature management. ZZ2 is currently involved in several nature management programmes, combining both plant and wildlife mangement in areas spanning 20 000 ha.

By engaging the community living in the Mooketsi area and surrounds, ZZ2 is in the process of solving bush densification on some of its land in the Limpopo province. Farming methods employed many years ago resulted in over-grazing of the land, preventing veldt fires occurring and, combined with the withdrawal of large herbivores, this  has led to extreme bush densification.

The densification creates several problems: Firstly, the areas that can be inhabited by grazers are reduced because the bush stifles grassland and, secondly, the movement of remaining wildlife and visibility for tourists are reduced to almost zero. Water absorption of the soil is minimised, leading to soil deterioration and erosion.

A lot of research has been done into bush densification, but according to Riaan Drotsky, head of nature mangement at ZZ2, there is not a one-size-fits-all solution to this problem.

ZZ2 approached this particular  challenge by first conducting a small feasibility study where people from the community were brought in to the nature conservation areas to cut down the bush (consisting mainly of sicklebush, Dichrostachys nutans and certain Combretum and Acacia species). This resulted in increased visibility and wildlife carrying capacity, but the effect did not make alasting difference.

It was then decided to involve the community on a large scale. Members of communities living adjacent to ZZ2’s land are now offered the opportunity to cut wood from designated areas, bar certain protected species and any tree with a circumference larger than that of a 2 litre cold drink bottle. This measurement is used because it makes it easier for the people doing the cutting to visualise the size of the bush that can be cut and to know which trees to leave.

The bush eradication project has offered the community an opportunity to come in and cut down the bush for their own gain - be it to sell the wood or to use it themselves for heating and cooking. Community members use their own equipment and transport and are also responsible to apply for permits from the Limpopo Department of Nature Conservation to transport wood.

The clearing of the bush takes places systematically in blocks and these are completely cleared before new blocks of land are opened up for cutting.

This project has resulted in a win-win situation for all parties involved – benefiting both ZZ2 in its quest to manage bush densification, as well as the community who gain financially from cutting the wood. Riaan says that the project has had an unbelievably positive effect on the densification, as well as on the socio-economic circumstances of the surrounding communities. On any given day there are in excess of 700 people cutting wood in a specific block – an amazing sight to behold. Previously unemployed people now have the opportunity to earn money, while assisting ZZ2 in its quest to rehabilitate nature.

Wood is a scare resource in the community and this project has seen a great entrepreneurial spirit developing amongst community members. In some case an individual will employ up to 30 or 40 people (mostly women) to cut the bush, paying them and then selling the wood. It is also interesting to note that the policing of the sites – checking to see that only permissible species of the right size are cut – has mainly been taken out of the hands of ZZ2, as the community has become totally self-regulating. Community members have appointed their own gate guards to check loads leaving the areas and if people are caught not complying they are barred by the community to enter the site again. The financial attractiveness of the opportunity outweighs the risk for all in cheating.

ZZ2’s nature management teams follow up by treating the stumps to prevent re-growth. The long term aim is to re-establish the original grassland in the areas and to bring the appropriate wildlife back to where they roamed freely many years ago.

How does nature management relate to ZZ2’s core business – that of farming tomatoes, onions, avo’s and more?  Riaan says that managing nature effectively impacts on adjoining farmland. For example, well managed natural areas lead to increased birdlife and insect life that benefit adjacent farm land. This is in line with ZZ2’s value system of working with nature, instead of against it and forms part of its Natuurboerdery principles. Riaan adds that if an area is managed ecologically you always have a reference to see what it looked like in its natural state before farming took over. This facilitates nature management in all its facets. Riaan is adamant that every piece of land in South Africa needs to be optimally productive– be it for farming or nature conservation. Letting land deteriorate away from its potential is unsupportable.

By optimally managing all the scarce resources of water, soil and biodiversity, ZZ2 creates a biosphere where natural areas, the community and farming activities are all managed ecologically and in harmony with each other.

 

Soil health: The key to ZZ2’s productivity

To increase agricultural productivity, ZZ2 approaches soil health management holistically. This approach implies optimising and integrating the chemical, physical and biological properties of soil. According to Bombiti Nzanza of ZZ2’s agronomy department, this holistic approach to soil health was developed over the years and was affirmed by ZZ2’s visit to Cornell University in the USA in June last year.

In the past ZZ2 placed emphasis mainly on the biological components of soil such as fungal or bacterial ratio to determine whether it could be considered healthy or not. However, a presentation by Prof. George Abawi of the Cornell Soil Health Program Work Team two years ago set the ball rolling towards a more holistic and integrated approach towards soil health comprising the chemical, physical and biological components of soil.

The Soil Health Program at Cornell offers training on an annual basis and a number of ZZ2’s agronomists were invited to attend these workshops. According to Nzanza, the first step in the training was to identify soil constraints. These constraints can take many forms, including soil degradation, soil compaction, low cation exchange capacity (CEC) or soil-borne diseases.

Once the soil constraints have been identified, priorities are set to solve these problems. Soil management practices are then implemented. These could, for example, include the planting of cover crops, minimum tillage or the use of compost. A third element in soil health management is to compile a history of the soil so that it becomes clear what happened with the soil in question in the past. The final step is to select the most appropriate soil management practices to remedy the problem.

According to Nzanza there are currently four main strategies that could be followed to manage soil health. The first is to plant a cover crop – usually early grasses or legumes - to improve soil health. Marigolds can, for example, help to alleviate a problem with nematodes, whereas other plants can help the soil to retain nutrients. Secondly, organic amendments can be used such as compost or manure. The third strategy is to look at tillage and apply minimum tillage, if appropriate. The final strategy is to look at crop rotation. This could pose a problem at ZZ2, as the lands in question bear a mono-crop, namely tomatoes.

Nzanza stresses that it is not necessary to apply all four of these strategies at once. If one – such as crop rotation, for example – is not viable, the other strategies can be implemented.

One of the soil health management strategies that do not fall within the four mentioned above is microbial inoculants. This is widely used at ZZ2.

Nzanza is of the opinion that the most important new process brought back from the USA is the implementation of the Cornell Soil Health Tests.   Previously the agronomists at ZZ2 would take soil samples which would be analysed for their chemical properties at ZZ2’s soil health laboratory. In certain cases the soil biology would also be analysed. The Cornell Soil Health Tests, however, do not look at these analyses in isolation, but rather propose that the chemical, physical and biological make-up of the soil should be analysed in an integrated way to get the best solution to solving soil health problems.

Finally it is important to remember that the aim of all of these strategies mentioned is to improve soil health which in turn would lead to improved crop productivity. 

The cooperation between ZZ2 and Cornell is ongoing. At the moment the ZZ2 agronomists are collecting data to contribute to Cornell’s research. It is hoped that more scientific papers on soil health will see the light in the near future due to this partnership.
 

 

ZZ2 forges a link between academia and the agricultural industry

Earlier this year Prof. Janice Thies of the Cornell University in the USA brought a group of graduate students to ZZ2 to investigate possibilities for further study and cooperation with this South African farming conglomerate.

Prof. Thies, associate professor of Soil Biology in Crop and Soil Sciences and director of Graduate Studies for the field of Soil and Crop Sciences, became familiar with ZZ2's Natuurboerdery focus to commercial farming when she was a speaker at a soil symposium at the University of Stellenbosch.

During her first stay in South Africa, Prof. Thies visited ZZ2's farms in Ceres and Mooketsi and was most impressed with ZZ2's focus on soil as a resource base for sustainable farming. She saw the possibilities of bringing graduate students from a variety of disciplines to South Africa to investigate themes for further study.

Says Prof. Thies, "There has always been a disconnect between academia and the agricultural industry. I see the collaborative linkage between ZZ2 and students from Cornell as a perfect opportunity to bridge this divide. "

Prof. Thies describes ZZ2's Natuurboerdery as intelligent agriculture as it moves away from chemical farming practices towards organic farming, while keeping commercial viability in mind. The fact that ZZ2 is commercially successful in a socially responsible way offers a model that can be implemented in other parts of the world.

The group of students represented a variety of disciplines, including agriculture, crop and soil science, social studies and international agriculture. During their visit three or four students identified topics for Masters' theses which will be pursued at ZZ2 in the near future.

"This initial contact has opened up vast opportunities for student exchange between the USA and South Africa", says Prof. Thies. "ZZ2 is an ideal living laboratory where students can gain expertise and conduct research in the field."

 

ZZ2 Pinzgauers beef up Pretoria Show

ZZ2's prime Pinzgauer stud performed exceptionally well at this year's Pretoria Show. Amongst 150 entries from 25 Pinzgauer breeders,  ZZ2's Mister Silence was judged champion interbreed bull, the overall meat cattle champion bull, as well as the general gold cup winner at the show.  Tami Ramathwala was awarded best cattle handler overall.

The Pinzgauer Championships was held on 1 September in the mother city and was the final in a series of five agricultural shows in which Pinzgauers participated; the others being the Vryburg Show, the Bloemfontein Show, the Royal Show in Pietermaritzburg and the Thabazimbi Show.  It is the first time that a gold cup winner - chosen from all the participating meat cattle breeds - was appointed at the Pretoria Show.

ZZ2 added to the Bertie van Zyl Pinzgauers stud in 2006 when CEO Tommie van Zyl and Paul Bester, general manager of cattle husbandry at ZZ2 bought in a new bloodline from Namibia. This stud is known as the Grootboom stud.

A Pinzgauer stud has now also been established on ZZ2's farms in Ceres in the Western Cape. This breed, originally from Austria, is very adaptable to different climates. With the establishment of the breed in the Western Cape the genetic pool has been extended, not only for ZZ2 but for all Pinzgauer breeders.
