Offered Papers Theme B: Grassland and the Environment
Description
Chemical fertilisers are expensive and can cause environmental contamination, affecting the biodiversity; it is therefore desirable to use organic manure that is cheaper and can be prepared on the same farm. Earthworm manure is the product of worms that transform organic matter (Salinas & Rojas, 1995), which improves the physical, chemical and biological properties of the soil (Pérez, 1993; Ravera & De Sanso, 1999). The importance of these improvements justifies the use of the worm humus in fertilisation programs in grasslands. Therefore, the objective of this experiment was to evaluate the effect of the earthworm manure on the biomass production and minerals concentration of Digitaria swazilandensis.
