Rice and wheat residues straw N-mineralization immobilization
2011/2/22
A laboratory incubation experiment was carried out for 85 days to monitor the N mineralization during the decomposition of 15N labeled wheat and rice straws incorporated at 5 g kg-1 soil at varying te...
Maize yield response to the combined application of Tundulu rock phosphate and Pigeon Peas residues in Kasungu, Central Malawi
Malawi maize rock phosphate biomass Cajanus cajan
2011/1/11
Malawi is endowed with several large deposits of rock phosphate (RP) occurring in the southern part of the country that remain unexploited due to limited knowledge on their agronomic usefulness.
A field experiment was conducted to assess the persistence of 2,4-dichlorophenoxy acetic acid (2,4-D) and the consequent changes in microbial populations in the wetland paddy soils of Thrissur, Kera...
