A laboratory incubation experiment in a completely randomized design with three replications was carried out for 90 days to test the effect of zeolite and biochar application to calcareous sandy loam soil on potassium forms distribution and its release rate. The treatments included (1) Absolute control (C), (2) 10 g kg-1 zeolite (Z1), (3) 20 g kg-1 zeolite (Z2), (4) 10 g kg-1 biochar (B1), and (5) 20 g kg-1 biochar (B2). After incubation period, the concentrations of soluble, exchangeable, and non-exchangeable K and the release rate of K to 0.01 M CaCl2 during 200 min (10 successive extractions for soil samples of 20 min for each using CaCl2 solution) were determined. Results showed that zeolite application increased the soluble and exchangeable K concentrations. However, amending soil with biochar had a positive effect on all K forms. Addition of zeolite or biochar increased the cumulative K release. The parabolic diffusion, power function and Simple Elovich models described the kinetics of K release to CaCl2 solution well from all the soil treatments. Zeolite and maize stalks biochar may have an effective role in improvement of K availability and release in the calcareous sandy loam soil as well as may aid in increasing the ability of this soil to supply the different crops with K.

Leaching loss of nutrients hampers plant growth and contributes to environmental pollution. An experiment was conducted at the net house of Soil Science Department, Bangladesh Agricultural University, Mymensingh during January to May 2009 to find out the leaching loss of N, P, K and S from sandy loam soil. Each pot received 6.67 kg dry soil with an opening at the bottom for collecting leachates. Six treatments were used: T0 = control, T1 = NPKS (120, 25, 60 and 20 kg ha-1), T2 = NPKS (180, 37, 90 and 30 kg ha-1), T3 = NPKS (90, 5, 28 and 17 kg ha-1) + cowdung (2.5 t ha-1), T4 = NPKS (109, 25, 60 and 20 kg ha-1, N as USG) and T5 = as T1 but N applied as foliar spray. Treatments were arranged in a completely randomized design with three replications. Leachates were collected at 15 days interval for determination of NPKS. The total leaching loss of N, P, K and S due to different treatments ranged from 16.00 to 90.21, 0.07 to 0.29, 9.60 to 11.20 and 3.75 to 17.81 kg ha-1, respectively. Application of chemical fertilizer at higher rates resulted in greater loss of nutrients. Integrated fertilizer management with cowdung (T3) minimized such losses. Use of USG also reduced leaching loss of N, P, K and S. The application of cowdung and USG with recommended balanced fertilizer might be useful for minimizing N, P, K and S loss from wetland rice field.Bangladesh Rice j. 2016, 20(1): 59-64

Ammonium applied alone or after addition of K depressed the uptake of K by oats grown in a sandy loam soil in the greenhouse. When NH4 was added first and K later at seeding, however, NH4 increased K-uptake.In the absence of K fertilizer, NH4 reduced the release of non-exchangeable K to the plants. When added prior to or at the same time as K at seeding, NH4 reduced K-fixation. This inhibitory effect of NH4 on fixation of added K was reflected in higher amounts of K in solution as shown by lower [Formula: see text] ratios. These results of chemical extraction of the soil indicated that the effects of NH4 on K-uptake by the oat crop arose from reactions in the soil.

Background: This study aimed to determine the pattern of N mineralization of tithonia (Tithonia diversifolia) and sugarcane (Saccharum officinarum) leaves and assess the uptake of N nutrients in maize by giving T. diversifolia and S. officinarum leaves with different qualities on sandy loam soil. Methods: The research used a completely randomized design (CRD) with following treatment: T1 (100% T. diversifolia), T2 (100% S. officinarum), T3 (75% T. diversifolia: 25% S. officinarum), T4 (50% S. officinarum: 50% T. diversifolia), T5 (25% T. diversifolia leaves: 75% S. officinarum), T6 (without T. diversifolia and S. officinarum or control). Result: The results showed that the N mineralization pattern of the organic matter combination was significantly higher than the control for all observations. The amount of N mineral released in each treatment was T1 (54.58-529.7 mg/kg), T2 (41.80-381 mg/kg), T3 (47.69-473.6 mg/kg), T4 (46.70-424.0 mg/kg), T5 (70.69-378.9 mg/kg) and T6 (47.14-303.6 9 mg/kg). The sequence of cumulative N release during 12 weeks of incubation was T1 (529 mg/kg) greater than T3 (573.6 mg/kg) greater than T4 (424.0 mg/kg) greater than T2 (381 mg/kg) greater than T5 (378.9 mg/kg) greater than T6 (303.6 mg/kg). These results suggested that T. diversifolia and S. officinarum leaves significantly increased N nutrient uptake in maize by 125% to 144.54%.

The change in the microbiological activity of sod-podzolic sandy loam soil when using coffee waste and sewage sludge as a fertilizer for oats in comparison with traditional fertilizers is considered. During the study, it was determined that the predominant groups were bacteria and actinomycetes. Bacilli and fungi are few in number. The introduction of sewage sludge and coffee waste into the sod-podzolic sandy loam soil at a dose of 10 t / ha increases the activity of the microflora of the sod-podzolic sandy loam soil, which increases the effective and potential fertility.
