2.1 Breve descripción del Enfoque

Enrichment of tropical agicultural soils with local available organic matter in the cerrado agroscape, Brazil.

2.2 Descripción detallada del Enfoque MST

Descripción detallada del Enfoque MST:

Aims / objectives: Use local available organic matter (OM) to enrich Tropical agricultural soil (Ferrasol) as a strategy for sustainanle land use to improve efficiently soil fertility and/or crop production in the Brazilian Cerrado agroscape. The applied OMs are either cost-efficient or waste materials from nearby industrial suppliers.

Methods: We applied three different types of OM amendments. They include (a) Filter cake of sugarcane residues (Saccharum officinarum from alcohol/sugar-production, (b) sawdust of Peroba and Cedrinho (Peroba jaune and Erisma uncinatum, respectively) and (c) coarse chips of Eucalyptus sp.

We added 0 (control), 6, 12 and 18 tons of each amendment per hectare; using two disposition methods: direct on the soil and with harrow incorporation. Each treatment was done in triplicate. Subsequent to the first amendment application; there have not been further experimental OM additions. The experimental site was not fenced to allow the land user to continue with their arable field routines on all treatment plots.

By sampling soil and biomass, we have assessed the effect of OM addition on soil organic carbon, nutrients, water holding capacity and crop (soy and corn biomass and grain) production, after one, two and three years of a single application.



Stages of implementation: The experiment was set up in February 2012. The last soil and biomass sampling was carried out in February-March 2015.

Role of stakeholders: Mr. Antonio Huebner, owner of the Farm Rio Engano, provided us an experimetal area in his farm.
The local industies supplied the applied OM amendments.
Professors and researchers from the Christian-Albrechts University of Kiel (CAU Kiel), Federal University of Mato Grosso (UFMT) and François Rabelais University have given academic and scientifical support to the approach.


Other important information: From our outcomes, we intend to provide information for the development of soil C-enrichment schemes and carbon-friendly landscape management programs for land users, applying local resources in the Brazilian Cerrado.

2.7 Tipo de Enfoque

• proyecto/ basado en un programa

2.8 Propósitos/ objetivos principales del Enfoque

The Approach focused mainly on SLM with other activities (crop production)

We aim to identify a feasible combination of types, amounts and disposition methods of OM amendments to improve efficiently soil fertility, carbon stock and/or crop production in the Brazilian Cerrado agroscape.

The SLM Approach addressed the following problems: Croplands have shown a reduction of organic matter, due to some traditional agricultural practices, such as soil plowing and tillage. These practices break down soil aggregates and expose organic matter to microbial decomposition, causing its loss to the atmosphere by mineralization (Zech et al. 1997; Tivet et al. 2013). It is especially critical in soil (Ferrasol) from the Brazilian Cerrado, as its OM content is relatively low, and tropical temperatures and humidity accelerate microbial activity (Price and Sowers 2004).

6.4 Fortalezas/ ventajas del Enfoque

Fuerzas/ ventajas/ oportunidades desde la perspectiva del usuario de la tierra
The approach improves soil quality and could enhance crop resilience in dryer years.

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave

As this approach uses industrial biomass residues, we consider it a win-win solution for organic matter waste disposition and to improve soil quality. (How to sustain/ enhance this strength: The costs of transport and application can limit the extensive use of soil organic matter enrichment practices among land users in the Brazilian Cerrado. Therefore, subsidies could contribute to the adoption of this approach by a broader number of farmers.)

6.5 Debilidades/ desventajas del Enfoque y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del usuario de la tierra

¿Cómo sobreponerse a ellas?

The costs of OM transport and application

Mr. Antonio Huebner, the land owner and user in this approach, has been cultivating with soybean and corn rotation under conservational farming practices, i.e. no-tillage, for more than 20 years. He thinks a possible more economic alternative for this approach is to create soy and corn varieties which have more abundant foliage and the same capacity of grain production. In an approach that combines these varieties and no-tillage, the farmers could continue cultivating in their traditional way, without having to incur in extra costs due to application of OM amendments; however, increasing organic matter inputs to the soil.

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
