“…Low OC content in most of the soils might be due to the fact that the farmers cannot apply manures or organic sources of nutrient at required level. These results were in conformation with the findings of Kavitha et al, (2019). The CV value of 36.50 per cent indicates that, organic carbon in the soils varied spatially in SNJ sugar factory zone.…”

“…The variation in soil pH might be attributed to the variation in nature of parent materials and degree of weathering. The higher pH values could be ascribed to the comparatively less leaching of bases in sandy clay loams than that in other coarse textured soils (Kavitha et al, 2020).…”

A survey work was conducted to assess the soil fertility status of sugarcane growing soils of SNJ sugar factory zone, Andhra Pradesh. Two hundred seventeen (217) soil samples were collected at a depth of 0-15 cm from nine mandals (Palasamudram, Veduru Kuppam, Penumuru, Rompicherla, Pileru, Pulicherla, Chinnagottigallu, Erravaripalem and Chandragiri) and analyzed for physicochemical and chemical properties. Geo reference coordinates (Latitude and Longitude) also noted at sampling sites. The results revealed that 38% of soils were neutral in reaction (pH 6.5-7.0), 10% were slightly acidic and 33% of soils were slightly alkaline in reaction. All soils had non saline nature. 80% of soils were low in organic carbon (OC) content and 20% of soils had medium in OC content. Available nitrogen in 93% of collected soils was low (< 280 kg ha-1). Available phosphorus in these sugarcane growing soils ranged from 26 to 114 kg ha-1 with a mean of 57.07 kg ha-1. Available potassium levels varied between 197 and 521 kg ha-1 (medium to high) with a mean of 347 kg ha-1. The soils have available sulphur ranged from 2.6 to 15.6 mg kg-1. 74% of soils were showed deficient in available sulphur. Digital soil maps for pH, EC, OC, available nitrogen, phosphorus, potassium and sulphur prepared by using GIS approach. Soil nutrient index for OC, available nitrogen, phosphorus, potassium and sulphur was 1, 1, 2, 2.31 and 1, respectively

“…The samples sufficient in DTPA Fe were further categorized into four sub classes having limits of DTPA extractable Fe viz., 4.5 -9.0, 9.0 -18.0, 18.0 -27.0 and >27 .0 mg kg -1 and the samples under these categories were found to be 10.5, 70.5, 15 and 14%, respectively (Table 3). The sufficiency of Fe in soils might be due to the amount of iron required by crops is being released by Fe bearing minerals viz., hematite and goethite in these soils [18].…”

Sugarcane is the most important commercial crop grown in India and plays vital role in agricultural and industrial economy. In Andhra Pradesh, more than 50% of sugarcane is produced from Chittoor district for sugar and jaggery production. Sugarcane is heavy nutrient requirement crop and also removes considerable amount of nutrients through biomass. Continuous application of straight fertilizers, limited use of organic manures as well as non recycling of crop residues causes micronutrient deficiencies in soil. Keeping this in view, the present study was taken up to study the physico-chemical properties and DTPA extractable micronutrients and mapping of these nutrients. Soil samples along with geo reference coordinates were collected and analyzed for physico-chemical properties and DTPA extractable micronutrients (Fe, Mn, Zn and Cu). The digital soil maps for DTPA extractable micronutrients were generated with geo reference coordinates by using GIS approach. The analytical data of soils in Sudhalagunta sugar factory zone, Chittoor district showed that 80% of samples were slightly alkaline in reaction followed by 13% of samples were neutral in reaction. Regarding electrical conductivity, 16% of soils were slightly saline in nature. Among micronutrients, except DTPA-Zn, all cationic micronutrients were existed in above critical limit in this factory zone, 11% of soils showed Zn deficiency. Similar trend was noticed in plant Zn content. 18.4% of plant samples showed Zn deficiency. Remaining micronutrients were in sufficient range. Digital maps for DTPA - Fe, Mn, Zn and Cu have prepared.

“…The majority of soils exhibited neutral to slightly alkaline reaction (6.6-7.8) (Table 2). This wide variation in pH (6.7 to 8.5) might be attributed to the nature of the parent material, climate of the region, organic matter and topographic situation [6,7].…”

One hundred soil samples from Rayal Cheruvu village in Ramachandrapuram mandal of Tirupati district, Andhra Pradesh were collected by using GPS to study soil fertility status. These samples were analysed for physico-chemical and chemical parameters. The results revealed that soils were slightly acidic to strongly alkaline in reaction and non-saline. Soil organic carbon was low to medium. The available nitrogen was low, the available phosphorus ranged from low to high and the available potassium ranged from medium to high. The fertility status was used to assess soil fertility constraints in the study area.
