“…Non-sulphate sulphur had a highly positive correlation with total sulphur (0.999). This might be due to the fact that all these forms are, by and large, interchangeable; thereby, showing a positive relationship to each other Das et al [16].…”

The present investigation was conducted to distribute and characterization of different Sulphur (S) fractions in selected soil orders of India. Soil samples were collected from cultivated fields in different states of India, covering West Bengal, Jharkhand, Bihar, Uttar Pradesh, Uttarakhand, and Himachal Pradesh. These states belong to the soil orders Entisols, Inceptisols, and Alfisols. A total of two hundred seventy composite soil samples were collected from ten locations of each order, representing three depths: 0-15 cm, 15-30 cm, and 30-45 cm, with thrice replication. After analyzing the various sulfur fractions, the results showed that there was no distinct distribution of sulfur reported in the various locations. In Entisols soil order, non-sulphate sulfur contributes highest fraction with a mean of 2744.99 mg kg-1 while lowest contribution was found in available sulfur with a mean of 25.24 mg kg-1 of total S followed by organic sulfur (112.54 mg kg-1), adsorbed sulfur (97.79 mg kg-1). A similar pattern was observed in Inceptisols and Alfisols soil orders. Available S was positive and significantly correlated with organic Sulphur in Entisol and Inceptisol while negative correlated with remaining fraction of S. Based on the sulfur availability index, the dominant fraction of sulfur in all three soil orders was non-sulfate sulfur.

“…Combined fertilizers have been found to have a signi cant bene cial effect on food production worldwide, and are an indispensable component of many agricultural systems [12].One of the reasons for lower productivity is imbalanced fertilization of N, P and K nutrients [13]. Namrata Kashyap in her experiment on hybrid rice [13] found that Nitrogen uptake was decreased by 16.93 and 28.30% with single application of P and K, respectively over combined application of N, P and K. According to Das and Basumatary [7]. in Rice plantation in Assam, Nitrogen uptake was decreased by 26.3 and 21.3% with single application of P and K, respectively over combined application of N, P and According to Dash [6], combined application of all the nutrients increased nutrient accumulation and uptake of rice plant in Odisha.…”

Based on a chemical examination of the soil, STCR is a quantitative method to suggest fertilizer doses for achieving the desired yield. The strategy is based on the presumption that a specific quantity of fertilizers must be ingested by the plant as absorption for the plant to produce a specific yield. To determine the amount of fertilizer required to produce a desired yield, the STCR technique develops fertilizer prescription equations that take into consideration the chemical properties of the soil. The approach has seen extensive application since it was developed as an AICRP project in 1967. The technique is predicated on the idea that the plant’s ability to absorb certain nutrients depends on the interaction between that nutrient present in the soil and in the applied fertilizer. Several studies support the idea that all the type of fertilizers used to feed the plant affects how much of a specific nutrient is absorbed. The reliability of fertilizer prescriptions made using the existing STCR approach is called into question because of the aforementioned shortcomings. We have created a new mathematical model for a targeted yield to address the shortcomings in the STCR technique. Data from carrot plantations were used to illustrate the model suggested by us.

“…Precision Nutrient Management: Future research should focus on developing precise nutrient management strategies tailored to DSR systems. This includes understanding nutrient release patterns from fertilizers under varying moisture conditions, optimizing nutrient placement for efficient crop uptake, and utilizing soil testing and remote sensing technologies to monitor nutrient status [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

Direct Seeded Rice (DSR) has emerged as a sustainable alternative to traditional transplanting methods, offering water and labor savings. However, the shift to DSR practices raises questions about soil health management. This review delves into the intricate relationship between nutrient dynamics and soil microbial communities in DSR systems. The review elucidates the impact of DSR on nutrient cycling, discusses the alterations in soil microbial diversity and functions, and explores strategies to enhance soil health in DSR. By addressing these aspects, the review offers insights into the complexities of DSR from a soil health perspective and highlights research gaps for future exploration.
