“…The available K showed positive relationship with pH (r=0.242**), OC (r=0.464**), CaCO 3 (r=0.211**) and N (r=0.388**). The results are clearly showed that the increases to Available K in soils also increases Available N. [49,50,51,39,38) also reported similar findings.…”

Farmers who want to improve nitrogen usage efficiency (NUE) and crop yield must have access to information regarding the geographical variability and distribution of soil parameters. Fertilizer application relying on soil characteristic maps and fertilizers recommendations may help reduce fertilizer input without sacrificing crop production. The current research focused heavily on evaluating the variability of soil fertility status in the Madhya Pradesh Gwalior region using geostatistical techniques. To do this, 150 GPS-based surfaces (0–15 cm) soil samples were obtained from the Gwalior region's five districts (Gwalior, Shivpuri, Datia, Guna, & Ashok Nagar) during crop harvest during the rabi season of 2019–20. Statistics and geo-statistics were used to analyze the results of the laboratory analysis. The analysis revealed that the soil samples' pH, EC, SOC, and CaCO3 values, respectively, varied from 4.40 to 8.30, 0.09 to 1.03 dSm-1, 2.0 to 10.60 gkg-1, and 3.0 to 24.0 gkg-1. In contrast, the amounts of N, P, K, and S that are present in soil vary from 102.0 to 356.0 kg ha-1, 6.0 to 61.0 kg ha-1, 114.0 to 896.0 kg ha-1, and 5.90 to 49.20 mg kg-1, respectively. Through building semi-variograms and mapping the data utilizing standard kriging techniques, the information was studied using both traditional statistics and geostatistics. For soil properties, semi-variograms were created, and their geographical distributions were delineated. The Nugget/Sill (Co/Co+ C) ratio for the modeled variables revealed moderate to high spatial dependences. The best-fit models for the reported soil characteristics were exponential, spherical, and circular. The findings of this research demonstrated that soil fertility quality varied significantly across the Gwalior area. This knowledge may aid in making choices about crop succession and the usage of plant nutrients to increase farmers' financial returns.

“…However, in both the years, total K was observed more under treatment T11 over rest of the treatments (Tables 2 & 3). Kori et al [42] reported 1.334% as the average value of lattice-K in vertisol. Jadhao et al [20] reported that the application of 100% NPK + FYM @ 5 t ha -1 significantly increased the lattice K (17078 mg kg -1 ) in 0-15 cm depth in Vertisol of central India.…”

A field experiment was conducted at the Research Farm of the ICAR-Indian Institute of Soil Science, Bhopal (India) to study influence of different integrated nutrient management (INM) modules on soil potassium (K) fractions. The experiment comprised with twelve treatments laid out in randomized block design (RBD) with three replications under maize-chickpea cropping sequence. The treatments included general recommended dose (GRD), soil test crop response (STCR) dose; combinations of inorganic and organic inputs and only organic modules. The soil samples were collected at crop harvest and analyzed for various K fractions viz., water soluble-K, available-K, exchangeable-K, HNO3-K, lattice-K and total-K. The results indicated that potassium fractions were significantly (p = 0.05) affected by different treatments. Different INM modules significantly enhanced significantly K availability in soil. Among various INM modules studied, treatment 11 (application of 20 t ha-1 FYM in maize with 5 t ha-1 FYM every year in chickpea) proved most beneficial for improving the soil K fractions. Findings of this type are important for K fertilizer management during crop production in areas with low soil fertility.

The present study was conducted at the experimental field of College of Agriculture, Indore during 2018-2019.Soybean (cv. JS-9305), was grown with 80 kg ha-1 seed rate with row to row and plant to plant spacing of 40 cm X 5 cm. Soybean crop was grown as per standard cultural practices. The experiment was conducted with nine treatments viz., T1- unfertilized control, T2- 20 kg N + 13 kg P ha-1, T3- 30 kg N + 20 kg P ha-1, T4- 40 kg N + 26 kg P ha-1, T5- 60 kg N + 35 kg P ha-1, T6- 6 t ha-1 FYM + 20 kg N + 13 kg P, T7- 5 t ha-1 crop residues + 20 kg N + 13 kg P, T8- 6 t ha-1 FYM and T9- 5 t ha-1 crop residues (CR) laid out in a randomized block design (RBD) having three replications. Different K fractions in soil sample viz., water soluble-K, available-K, exchangeable-K, non-exchangeable-K, lattice-K and total-K were determined following standard methods. The mean values were grouped for comparisons and the least significant differences among them were calculated at p<0.05 confidence level using ANOVA statistics. The results of present study revealed that to sustain K status in Vertisol there is a need of K application along with organic manure/crop residue. The application of organics with and without N and P application can sustain the Lattice-K availability in long run under soybean based cropping system of Vertisols. The rate of chemical fertilizer can be reduced up to 50% due to long term application of 6 t ha-1 FYM or 5 t ha-1 crop residues are added to soil.
