The Interaction between P Fertilizer and Vermicompost on the Availability, Fractions of P and (Zea Mays L.) Growth Indices in a Calcareous Soil
In order to increase the available Phosphorous (P), chemical fertilizers are applied; however, P chemical fertilizers are transformed into low available forms over time. Organic amendments could be effective in improving the efficiency of P fertilizers. The aim of this study was to investigate the effect of P fertilizers and vermicopost on the availability and fractions of P and maize (Zea Mays...
متن کاملEffect of Fertilizer and Soil Compactness Interaction on N, P and K in the Culture of Lawn
Under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. Once mineralizing occurs, mineral elements like P, S, Ca, Mg, K and other cations are released. A related study was conducted to determine the effect of seven organic fertilizers (Leaf Mold (LM), R...
متن کاملcumulative and residual effects of organic fertilizer application on selected soil properties, water soluble p, olsen-p and p sorption index
long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...
متن کاملP-211: The Effects of Vasectomy on Histological Structure of Epididymis and Testis in Rat Model
Background: Vasectomy is a simple and highly effective contraceptive method with a low morbidity rate and an extremely low mortality rate. during the past decade millions of men have undergone vasectomy, but there have been surprisingly few studies of morphological effects of genital organs after vasectomy. The most important issues about vasectomy are degenerative changes in testicular tissue,...

Long-term application of fertilizers containing P, especially organic fertilizers, usually increases the water soluble and available P of soil and at the same time may result in P accumulation in soil. Organic fertilizers may also increase movement of P in the soil profile that could result in surface and ground water pollution. An experiment was conducted on field plots that received three app...
