Extractable Phosphorus as Affected by Humic Acid Application in Salt Affected Soils
To use of organic fertilizer sources for increasing crops production on sustainable basis has become imperative because the cost of chemical fertilizers is high. An experiment was conducted during 2006 on two saltaffected soils of District Charsadda to evaluate the effect of different levels of single super phosphate (SSP) alone and in combination with humic acid (HA) on phosphorus availability...
متن کاملDistribution of zinc and copper chemical forms and their relationship with some physico-chemical properties and clay minerals in some calcareous soils
Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
متن کاملThe Influence of Manure Phytic Acid on Phosphorus Solubility in Calcareous Soils
Manure characteristics can influence the potential for P transfer in runoff following land application of manures. This research assessed the influence of manure characteristics on P solubility in calcareous soils using manures from poultry (Gallus Domisticus) fed a variety of grain-based diets with the manures containing a range of total P (5.6–16.4 g P kg), water-extractable P (WEP, 0.9–4.7 g...
متن کاملInfluence of foliar and soil applications of iron and manganese on soybean dry matter yield and iron-manganese relationship in a Calcareous soil
Iron (Fe) and manganese (Mn) are essential nutrients for plants. Application of high levels of either Fe or Mn is often accompanied by relatively low levels of uptake for the other nutrient. The antagonistic relationship of these nutrient elements may occur either during absorption by roots or during translocation from roots to shoot. A greenhouse study was carried out to study the effect of so...
متن کاملEffect of Acidic Biochars on Some Chemical Properties and Nutrient Availabilities of Calcareous Soils
Low organic matter content and alkaline pH of calcareous soils in arid and semi-arid regions are the main reasons for the low nutrient availabilities for plants in these soils. One way to improve the chemical properties and fertility of calcareous soils is the application of organic substances such as biochar produced from pyrolysis of organic wastes. However, biochars have an almost predominan...
