PROCESS OF IMPROVED SEMI-STATIC COMPOSTING FOR THE PRODUCTION OF A HUMECTANT SUBSTRATE OF LOW DENSITY OF USE THEREOF IN NURSERIES AND GREENHOUSES |
摘要 |
<p>This invention comprises improved composting of cane sugar press mud and lignocellulosic materials. The result is a low density humectant substrate (SHBD) for use in agriculture. The process takes place in semi-static biopiles which are homogenized and aerated mechanically. The lignocellulose materials are added in a supplied batch system, in steps and doses which depend on the type of lignocellulosic material and the quality of the required final substrate. Another objective is to provide, within 8 weeks, a material without pathogenic microorganisms nor weeds, with low density (< 0.4 g/ml), high porosity (110%), and high water retention (> 90%), useful as a substrate in horticulture and forestry production in nurseries and greenhouses; or as a humectant and soil-improving agent in agricultural land and eroded soils. Said substrate has better physical, chemical and biological features for plant nutrition than equivalent substrates uch as peat and coconut fibres.</p> |
