To investigate the effects of different nutrient management regimes on the soil chemical, eco-enzymatic stoichiometric and microbial characteristics, soil samples were collected from a 30-year, long-term field experiment with six plots growing rice. The results showed that as integrated fertilization increased, so did the concentrations of soil total or available nutrients and microbial biomass...

The objective of this study was to evaluate effects of cow manure on soil hydraulic properties and bromide leaching in a sandy loam soil (coarse loamy mixed, Typic Torrifluvents). Manure was applied at 0, 30, and 60 tha-1 at three replications in a completely random design. Three months after manure application potassium bromide (KBr) at rate of 300 Kg ha-1 Br was uniformly applied on the surfa...

A greenhouse experiment was conducted using corn to study the effect of arbuscular mycorrhiza, organic matter and zinc (Zn) on chemical forms of Zn in a calcareous soil. Experimental setup was factorial, based on completely randomized design with 3 replications. Treatments consisted of 3 levels of Zn (0, 5, and 10 mg Zn per kg soil), 2 kinds of organic manure (sheep manure and municipal waste c...

A specific methodology for these activities has not been prepared because the contribution to total national emissions is thought to be currently insignificant, i.e. less than 1% of national emissions of any pollutant. If you have information contrary to this please contact the expert panel leaders.

The effect of organic manure and chemical fertilizers on vegetable crops and soil properties in the radish-stem amaranth-Indian spinach cropping pattern was studied in a homestead area of Gazipur district in Bangladesh. There were eight treatments poultry manure (PM) 5 t ha (T1), cowdung (CD) 10 t ha -1 (T2), household waste (HW) 10 t ha -1 (T3), PM 2.5 t ha -1 + reduced RDF (recommended dose o...

On a survey during the period of 2006-2007 a number of tylenchids were found associated with Zea mays in Kashmir valley such as Pratylenchus sativus kaul, 1985, Aphelenchoides srinagrensis Kaul, 1985 and Tylenchorhynchus zeae Sethi and G. Swarp, 1968. These species were found to have morphometric variations probably due to habitat alteration from the originally described ones. As a part of the ...

Organic farming avoids the use of synthetic fertilizers and promises food production with minimal environmental impact, however this farming practice does not often result in the same productivity as conventional farming. In recent years, biochar has received increasing attention as an agricultural amendment and by coating it with minerals to form biochar-mineral complex (BMC) carbon retention ...

Compost and sewage sludge contain high concentration of plant nutrients and, thus, have been used extensively as an inexpensive fertilizer. The objective of this study was to evaluate cumulative and residual effects of compost, sewage sludge and cow manure on nitrogen, phosphorus and potassium in soil and wheat. The experiment included compost, sewage sludge and cow manure, each applied at 3 ra...
