Evaluation of Poultry Manure Application Rates on the Nutrient Composition of Dioscorea bulbifera (Aerial yam)

Brazil is one of the leaders in the production and trading of tobacco leaves in the global market, which results in a large amount of residues that would be recycled and used as soil fertilizers in agriculture. This research aimed to study the land disposal potential and agricultural use of tobacco processing residues (TPRs), their mineralization and the nutrient supply to the plants. The study was carried out in an open area using pots with 32dm³ of a sandy soil (Paleudult), provided with water drainage collectors and tilled with three corn plants each. Eighteen treatments were tested with mineral fertilization, poultry manure (PM), earthworm compost (EC) and increasing rates (0, 7.5, 15, 30 e 60t ha-1) of TPR D (dust) and TPR S (stem fibers).Treatments with TPRs (15t ha-1) plus mineral supplementation two by two (NP, NK and PK) were also tested, with four replications each. The experiment started in 01/15/2004 and conducted until 03/16/2004, when corn plants were harvested. The response curves showed that the residues application rates between 15 and 20t ha-1 are most adequate for the studied soil. The results indicated that both TPRs may be important sources of biomass and potash and have potential to be recycled in the soil, supplying part of the macronutrients required for proper plant growth.

Trace Element Uptake

Field experiments evaluated yield response to deep-pit poultry manure application to barley on a clay soil near Prince George and a grass-legume forage on a silty clay loam soil near Chilliwack, B.C. Substantial dry matter yield increases were measured at manure applications up to 20 t ha−1. Subsamples of both crops and the poultry manure were analyzed for Cu, Zn, Mn, Ba, Pb, Ni, Cr, Cd, B and Co. Selenium analyses were made on selected crop samples. There were no indications of toxicity problems even at 40 t ha−1, the highest application. Copper and Zn concentrations in forages were increased by the poultry manure and the Mn/Cu ratio tended to decrease with manure application.
