Soil compactibility as affected by soil moisture content and farmyard manure in central Iran
Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery traf®cking are major factors affecting soil conservation. In a ®eld experiment, cattle farmyard manure was applied to a silty clay loam soil (®ne-loamy, mixed, thermic Typic Haplargids, USDA; Calcaric Cambisols, FAO) in Isfahan, Iran. Three rates, 0, 50, 100 Mg haÿ1 (on oven ...
متن کاملBiochar affected by composting with farmyard manure.
Biochar applications to soils can improve soil fertility by increasing the soil's cation exchange capacity (CEC) and nutrient retention. Because biochar amendment may occur with the applications of organic fertilizers, we tested to which extent composting with farmyard manure increases CEC and nutrient content of charcoal and gasification coke. Both types of biochar absorbed leachate generated ...
متن کاملSoil Fertility, Phosphorus Fractions, and Maize Yield as Affected by Poultry Manure and Single Superphosphate
A field experiment was conducted in 2007 and 2008 on a slightly acidic alfisol. Poultry manure (PM) was applied at 0, 5 t ha(-1), 10 t ha(-1), 15 t ha(-1), and 20 t ha(-1) in combination with SSP at 0, 15 kg P ha(-1), 30 kg P ha(-1), 45 kg P ha(-1), and 60 kg P ha(-1), which was replicated three times. The pH and organic C were significantly increased by the application of PM alone while availa...
متن کاملColloidal and dissolved phosphorus in sandy soils as affected by phosphorus saturation.
Fertilization exceeding crop requirements causes an accumulation of phosphorus (P) in soils, which might increase concentrations of dissolved and colloidal P in drainage. We sampled soils classified as Typic Haplorthods from four fertilization experiments to test (i) whether increasing degrees of phosphorus saturation (DPS) increase concentrations of dissolved and colloidal P, and (ii) if criti...
متن کاملWASTE MANAGEMENT Soil Properties as Influenced by Phosphorus- and Nitrogen-Based Manure and Compost Applications
posting has some disadvantages that include nutrient and C loss during composting, the cost of land, equipManure or compost application based on N needs of corn (Zea ment, and labor required for composting, and odor assomays L.) may result in soil accumulation of P, N, and other ions, ciated with composting. since the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio...
