This work was carried out to comparatively study the chemical properties of 04 organic fertilizers made from sheep manure with crop residues such as corn, rice straw, sugar cane and kudzu. Looking for the best performance in the Miraflores estate of the UNSM-T, located 5 km from the district of Tarapoto, following the road to Belo Horizonte, in the Banda de Shilcayo district, province of San Martin and San Martin region.

Of the evaluations were obtained: The decomposition temperature ranged between 30-43 ° C. For the parameters of pH, EC, OM, CaCO3, N, Ca, Mg, CEC, salinity, C / N, all treatments are equal. As to P2O5, treatment with 1,370% T3 ...
