Organic manure contributes carbonaceous matter to soil, which when decomposed, offers mineral nutrients plants, also acts as a base exchange material, and helps improve the physical, chemical, biological aspects of soil. This study was conducted assess amount total nitrogen, available phosphorous, potassium, pH, under various organic sources. Collected samples were tested for phosphorus, soil m...
introduction: the spatial variability of soil properties and its importance in production is a matter-of-debate. insight about the variability of soil properties as well as the yield of orchards is necessary to achieve higher productivity and better management. orange is one of the most important export products in our country and to sustainable production of this product, it is necessary to id...

Energy crops have proved to be a viable alternative fossil fuels. However, high biomass production always means that large quantities of nutrients from the soil are removed at harvest. The goal this work was estimate nutrient (nitrogen, phosphorous, potassium) use efficiency (NUE) and nitrogen balance in an eight-year-old Populus deltoides clone Lux, short rotation forestry under two cutting cy...
A field experiment was conducted to study The effect of the application method and different doses phosphate solubilizing bacteria (PSB) phosphorus levels on sunflower during Rabi, 2020 at College Agriculture, PJTSAU, Rajendranagar, Hyderabad. laid out in Randomized Block Design, comprising eleven treatments with three replications. Initial soil parameters experimental site indicated that belon...
METHOD Eighty patients were prospectively randomized for precolonoscopic cleansing either with 750ml of 10% mannitol (Group M) or 180ml of a sodium phosphate preparation (Group NaP). Laboratory examinations before and after preparation on all patients included hemoglobin, hematocrit, sodium, potassium, phosphorous, calcium and serum osmolarity. A questionnaire was used to assess undesirable sid...
INTRODUCTION The pathophysiology of urolithiasis in infancy is not well known. The aim of this study was to investigate whether infants with urolithiasis have higher serum levels of vitamin D, as a possible risk factor for urolithiasis, compared to infants without urinary calculi. MATERIALS AND METHODS In this case-control study, 36 infants with urolithiasis (age range, 2.5 to 24 months) were...
A near infrared reflectance spectroscopy (NIRS) method for rapid determination of nitrogen, phosphorous and potassium in diverse meadow grasses was developed with a view towards utilizing this material for biogas production and organic fertilizer. NIRS spectra between 12,000 cm(-1) and 4,000 cm(-1) were used. When validated on samples from different years to those used for the calibration set, ...
