Assobari is the association for sugarcane suppliers in Bariri, in the São Paulo state of Brazil. It brings together farmers to defend their interests, share knowledge and offer technical and social support.

The project is run in partnership with Coopercitrus, a Brazilian cooperative in the commercialisation of agricultural inputs, machines and implements.  It has a membership of 38,000 farmers across various crops.

Purpose of the project

The project aimed to test no-till and Integrated Crop – Livestock – Forestry Systems in sugarcane and identify the productivity and sustainability benefits. 

No-till farming is the practice of planting crops without digging, stirring, and turning the soil over.  

Integrated Crop-Livestock-Forestry Systems (ICLFS) is an agricultural production approach that integrates different production systems – agricultural, animal farming and forestry – within the same area. It can be done through intercropping, crop succession or crop rotation, so that all the activities are mutually beneficial. They aim to optimise land use and increase productivity. 

Location

Brazil is one of the world’s largest producers of sugarcane, standing out in the production of sugar and ethanol in an area of approximately 8 million hectares. The most important regions are Central-South and parts of Central-West, the latter are where Assobari concentrates its operations.

The project was carried out in two sugarcane plantation areas, owned by smallholder members of Assobari who are passionate about research and innovation. Their plantations have different soil types which allowed comparison.

Why this project?

The Bonsucro Impact Fund supports collaborative, scalable and innovative projects that accelerate sustainable sugarcane production.

Scalability

Once identified, the best practices and treatment options were shared with Assobari members and the participating cooperative to multiply such results in their areas. 

Innovation

The project in no-tillage and ICLFS is fundamentally based on crop rotation and permanent soil cover. No research has been published on this type of work to date.   

This initiative was unprecedented as it sought to combine the fundamental concepts of a conservationist and sustainable system, enhanced with humic* and biological products for sugarcane farming.

Sustainability

The principle of inter-cropping, which is possible in the planting period of the sugarcane can bring direct and indirect benefits like soil cover, increased soil permeability, lower risk of soil erosion, higher nitrogen fixation of the soil, increased soil biological life. 

Expected outcomes

  • Improved soil health in sugarcane plantations through a lower use of inputs and agrochemicals, crop diversity and no tillage.
  • Positive financial impact on farmers through higher quality and yields, reduced costs and business growth opportunities.

Project results


Expected:
Improved soil health in sugarcane plantations through a lower use of inputs and agrochemicals, crop diversity and no-tillage.
 
Achieved:
Results showed that soil health was improved, weeds and pests were naturally reduced and inputs and agrochemicals use was reduced.
 
Expected:
Positive financial impact on farmers through higher quality and yields, reduced costs and business growth opportunities.
 
Achieved: 
Due to the high price of biological inputs in Brazil, the farmers didn’t see a reduction in their costs (intercropping costs 7% more). This was compounded by the cane yield not being improved across all treatment plots.
 
Learnings: 
The results of the experimental plots show that more testing is required to determine the best intercrops to accompany sugarcane (the ones chosen reduced the sugarcane yield).
 
The project team also concluded that the intercrop species should be planted before the cane.
 
The associate farmers were very interested to see the tangible change in the improved health of the soil and the natural reduction of pests.
