Soil Fertility Status

Soil test-based fertility management is important for sustainable soil management. This study was carried out to determine the soil fertility status of the Agriculture Research Station, Belachapi, Dhanusha, Nepal. Using soil sampling auger 25 soil samples were collected randomly from a depth of 0-20 cm. Soil sampling points were identified using GPS device. Following standard methods adopted by Soil Science Division laboratory, Khumaltar, the collected soil samples were analyzed to find out their texture, pH, N, P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu, Mn and organic matter status. The soil fertility status maps were made using Arc-GIS 10.1 software. The observed data revealed that soil was grayish brown in colour and sub-angular blocky in structure. The sand, silt and clay content were 36.03±3.66%, 50.32±2.52% and 25.42±2.25%, respectively and categorized as eight different classes of texture. The soil was acidic in pH (5.61±0.14). The available sulphur (0.73±0.09 ppm) status was very low, whereas organic matter (1.34±0.07%), available boron (0.56±0.10 ppm), available zinc (0.54±0.22 ppm) and available copper (0.30±0.01 ppm) were low in status. The extractable potassium (95.52±13.37 ppm) and extractable calcium (1264.8±92.80ppm) exhibited medium in status. In addition, available phosphorus (33.25±6.97 ppm), available magnesium (223.20±23.65 ppm) and available manganese (20.50±2.43 ppm) were high in status. Furthermore, available iron (55.80±8.89 ppm) status was very high. To improve the potentiality of crops (maize, rice, wheat etc.) for studied area, future research strategy should be made based on its soil fertility status.

Soil Fertility Status

Organic materials in situ remaining paddy crops in paddy fields are much abandoned by farmers. Most of the remaining harvested are burned, stacked in the cultivated, or used for animal feed or as a fungus. Straw compost is source of Potassium (K) and Silica (Si). About 80% of K absorbed by plants is in the straw. The return of straw to the soil may slow the impoverishment of Potassium (K) in the soil. This study aims to find out how the availability of phosphorus (P) and potassium (K) nutrients by giving organic matter as soil fertility status in paddy fields in Beringin Subdistrict, Deli Serdang Regency and to review management alternatives that are in accordance with the soil fertility status in the Central Land Rice fields in Beringin Subdistrict, Deli Serdang Regency. This research was carried out in the Central Rice Field in Beringin Subdistrict, Deli Serdang Regency ± 11 meters above sea level. The taking of soil samples was taken in the upper layer at the top soil depth of 0-20 cm, 20-40 cm and the coordinates were recorded using GPS (Global Positioning System).

Soil Fertility Status

Tree cropping has been known to bring about changes in edaphic component among other components of the ecosystem through their interactions with the soil and soil faunas. Premised on this, this study assessed the effects of sole cropping of teak and intercropping of cocoa and kola on the soil fertility status. The study was carried out using stratified-randomed sampling technique for the study plots in all the sampling sites. Three sampling sites consisting of four (4)-4oo m2 sampling plots each were established in which vegetation and some soil parameters were assessed. Results analysis showed that the synergistic interaction of leaves decomposition of cocoa and kola improved the organic matter content of the soil under the cocoa/kola site. Considerable improvement in soil fertility was enjoyed in the cocoa/kola site due to the large girth sizes and basal area of trees present in the cocoa/kola site while soil under the sole cropping of teak was impoverished. The degradation effects was due to the high rate of nutrient uptake of the teak, organic matter content was high in the forest site (9.12%) and cocoa/kola site (7.34) while the least was in the teak site (3.04%). A very strong correlation existed between organic matter content and some vegetation parameters.

Aims: A field experiment was conducted to evaluate soil fertility status, nutrient uptake, growth and yield of African marigold (Tagetes erecta Linn.) as influenced by fertilizer management with or without foliar spray of plant growth promoting chemicals. Study Design: The field experiment was conducted with eight treatments, each being replicated thrice in a randomized block design (RBD). Place and Duration of Study: Instructional cum research (ICR) farm, Assam Agricultural University, Jorhat, Assam (India), between September 2013 and January 2015. Methodology: The treatments comprised of an unfertilized plot, application of 2500 kg ha-1 vermicompost at planting followed by 10 kg ha-1 each of N, P2O5 and K2O in two equal splits at the time of planting and at 30 days after planting (DAP), 2500 kg ha-1 vermicompost as mixture with fertilizer (comlizer) 10:10:10 kg ha-1 (Comlizer-1) or 30:10:30 kg ha-1 (Comlizer-2) of N, P2O5 and K2O, respectively applied in two splits (planting and at 30 DAP). Each comlizer treatment had two supplementary treatments of spraying either vermiwash solution (10% on second and third weeks and 20% solution on fourth and fifth weeks after planting) or indole butyric acid (IBA) and kinetin mixture (IBA-kinetin) solution (0.01% each on second and third weeks and 0.02% each on fourth and fifth weeks after planting), respectively. Results: The soil pH, organic carbon and available phosphorous contents after harvest of the crop were not affected by the treatments. The available nitrogen content in soil significantly increased in comlizer-2, but the available potassium content was not affected by the fertilizer doses. The NH4-N and NO3-N in soil at 15 and 45 DAP increased significantly with application of comlizer-2. Phosphorous and potassium uptake by aerial biomass of marigold at 21 and 42 days after planting significantly increased in Comlizer-2, but the effect of foliar spray was not significant. The highest fresh flower yield was produced by application of Comlizer-2 with foliar spray of vermiwash, and differed significantly to the rest of the treatments. Conclusion: Application of mineral fertilizers as mixture with vermicompost and integrated with foliar spray of growth regulators showed promising results. Further works with higher doses of nutrient and compost, frequency and intensity of foliar application of growth regulators are required to develop cost effective nutrient management practice.

Soil Fertility Status

Abstract Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E. Assessment of soil fertility status based on the criteria of several soil chemical properties, CEC (cation exchange capacity), alkaline saturation, C-Organic, P2O5 (HCL, 25%) mg / 100g, and K2O (HCL, 25%) mg / 100g. The analysis results obtained from 11 sample points show that Aceh Besar has soil fertility status from medium to low.
