RESUMEN
Soil fertility evaluation of barren land is the most basic decision-making tool for an effective sustainable plan for a particular area. Thus, the present study was carried out to evaluate the soil fertility status in session variation of the two blocks of Kanpur Dehat (Akabrpur and Maitha). The soil samples were randomly collected based on the variability of land at a depth of 0-15 cm, 15-30 cm, and 30-60 cm in 5-5 sites in the both blocks. A GPS device was used to identify the location of the soil sampling points. Soil samples were analyzed for texture, pH, OC, EC, N, P, K, S, Fe, Zn, Cu, Mn, and exchangeable cations status following standard analytic methods in the laboratory of Soil Science and Agricultural Chemistry, C.S.A. University of Agriculture and Technology, Kanpur, UP. The soil organic carbon ranged from 0.18 to 0.34% of both blocks. Available nitrogen ranged from 102.78 to 138.39 kg ha-1, available phosphorous ranged from 9.89 to 16.47 kg ha-1 and available potassium ranged from 230.65 to 276.38 kg ha-1 in the surface soil of Maitha, all of which showed a decrease in value with increase in depth. Exchangeable calcium ranged from 4.58 to 6.34 (cmol (p+) kg-1), exchangeable magnesium ranged from 2.20 to 4.40 (cmol (p+) kg-1), and the pH of the soil in both blocks was highly alkaline in nature, all of which varied significantly with site and depth. The results indicated that soils are not good for the cultivation of various crops. Farmers are required to maintain Soil Health Card which helps them to adopt suitable management practices and provide proper nutrition to soil.
RESUMEN
The need for food and the expanding global population have put enormous pressure on agriculture to increase crop yield while preserving sustainability. Since rice is a staple diet for millions of people, novel methods are needed to increase yields without harming the environment. The possible advantages of using nano fertilizers in rice farming are examined in this abstract in order to raise yields, increase farmer profitability, and ensure long-term sustainability. Nano-sized carriers created for effective nutrient delivery to crops are called nano fertilizers, an innovative application of nanotechnology in agriculture. Their special qualities, such as their large surface area and regulated release mechanisms, allow for the targeted supply of nutrients to rice plants, improving nutrient uptake and utilization. Nano-fertilizers successfully optimize nutrient availability as a consequence, increasing crop output. According to studies, using nano fertilizers in rice farming increases grain yields because plants are better able to absorb and assimilate nutrients. The crop's resistance to environmental challenges and disease strains is strengthened as a result of this enhanced nutrient utilization, which also boosts yield and contributes to sustainable rice farming practices. Furthermore, nano fertilizers offer cost-effectiveness and increased profitability for farmers. Despite their initial higher cost, the efficient nutrient delivery of nano fertilizers reduces the overall application rate required compared to conventional fertilizers. This reduction in input costs translates to improved profitability for farmers, promoting economic sustainability in rice production.
