“…[2] The practice of crop residue incorporation needs a judicious supplementation with nutrients especially N and phosphorus (P). [3] This supplemented fertilizer N is necessary because soil microorganisms consume considerable amounts of soil mineral N needed for crop residue decomposition.…”

Low soil organic matter (OM) characterizes most soils of the humid tropics because crop residues are not returned to the field. A two-year (1997)(1998)(1999) field experiment was carried out in an Ultisol to determine the contribution of crop residue application in sustaining yields of maize (Zea mays L.) and groundnut (Arachis hypogaea) in a crop rotation system. Three management practices were compared, inorganic fertilizer with crop residues (T1), inorganic fertilizer without crop residue (T2) and half dose of inorganic fertilizer with crop residues combined with chicken manure (CM) (T3), in a randomized block design. During five crops cycle 1841 of continuous application of crop residues with inorganic fertilizers or combined with CM, 43% of the observed maximum yield of the maize was sustained compared to 21% in plots where crop residues were removed. Nitrogen (N) and potassium (K) uptake by the subsequent crops were significantly higher in crop residue treatments whereas phosphorus (P), calcium (Ca), and magnesium (Mg) were not significantly affected by application of crop residues. In the highly weathered soils of the tropics, incorporation of crop residues appeared to be a beneficial management practice for sustaining crop yields.

“…Retaining crop residues maintains soil fertility and may result in a slow build up of soil organic matter, thereby improving aggregation and water holding capacity of soils. Supplementing soil-applied crop residues with mineral fertilizers is necessary to hasten the decomposition process and is known to give higher benefits on soils of lower than those of moderate to high fertility levels (Salvatore & Sabbe, 1995;Belay et al, 1997): The aim of this experiment was to investigate the grain yield response of maize to application of crop residue and residual Nand P fertilizers on two soil types as influenced by soil and water conservation practices.…”

Field experiments were conducted on two soil types over a period of five years (1986)(1987)(1988)(1989)(1990) to investigate the effects of tied ridges and planting systems on the grain yield response of maize to applications of crop residue and residual Nand P fertilizers. Grain yields were increased by the use of tied ridges. Further increases in grain yields resulted from residual Nand P and crop residue applied separately or together. Under all fertilization practices, planting in the furrow of tied ridges resulted in higher grain yields than planting on top of tied ridges. The effect of the tied ridges in increasing grain yields was generally better in the drier periods and the more so when the ends of the ridges were tied. In wetter seasons the open end tied ridges gave higher yields than the closed end tied ridges. The effect of tied ridges on grain yield response of maize to application of crop residue and residual Nand P fertilizers was influenced by rainfall and by soil type.

“…Composting, a natural biological process, is the controlled decay of organic matter in a warm moist environment by action of bacteria, fungi and other organisms (22), under conditions favourable for them. The process can either be anaerobic or aerobic, but it is much faster and less odourferous if done aerobically.…”

Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste and paddy straw based co-composting system. The predominant microflora of the poultry manure were bacteria, fungi, enteric bacteria and spore forming bacteria whose population was high at the initiation of composting but decreased significantly as the compost approached maturity. The initial load of inherent enteric groups of bacteria in poultry waste, that also includes some pathogenic ones, is considerably reduced and some new vital groups contributed to compost quality as the microbiological biodiversity sets in the system and becomes stable. Major fraction of nitrogen of poultry waste was subjected to ammonia volatilization and a fraction of it conserved by cocomposting it in conjunction with wastes having low nitrogen contents. In the treatment T 1 and T 5 , where poultry manure and paddy straws alone were composted, 60 and 30 percent of organic carbon, respectively, was lost over a period of six months. Whereas in treatments T 2 ,T 3 and T 4, poultry manure and paddy straw were co-composted in the ratio of 3:1, 2:2 and 1:3, respectively, 51.4,45.0 and 37.0 percent of carbon, respectively, was lost during decomposition. The C: N ratio in all the treatments decreased significantly to 18.3 for T 1 , 24.7 for T 2 , 27.0 for T 3 , 34.9 for T 4 and 38.5 for T 5 at the end of composting period.
