Two hundred fifty geo-referenced surface soil samples (0-15 cm) from Tatrakallu village located in Scarce Rainfall Zone of Andhra Pradesh were collected at 250 m grid interval and analyzed for their fertility parameters. Analytical data was interpreted and statistical parameters like range, mean, standard deviation and coefficient of variation were calculated. Soil fertility maps were prepared for each parameter under GIS environment using Arc GIS v 10.3. Soils were neutral to strongly alkaline (6.49-8.90) in reaction, non-saline (0.01-0.84 dS m-1) and low to medium (0.3-7.0 g kg-1) in organic carbon. The soils were low to medium in available nitrogen (13-266 kg ha-1) and low to high in available phosphorus (2.0-91.0 kg P2O5 ha-1) and available potassium (0.4-628 kg K2O ha-1) and deficient to sufficient in available sulphur (0.1-50.1 mg kg-1). The wide variation from deficient to sufficient was observed in the status of DTPA extractable zinc (0.1-5.6 mg kg-1), iron (0.8-30.7 mg kg-1) and manganese (1.4-39.0 mg kg-1), whereas DTPA extractable copper (0.2-2.7 mg kg-1) was almost sufficient. The fertility status in Tatakallu village revealed that available N, S, Zn and Fe are important soil fertility constraints.","PeriodicalId":17302,"journal":{"name":"Journal of the Indian Society of Soil Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42089628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil was spiked with Ni @ 0, 10 and 25 mg kg-1 soil through its nitrate solution. Lime (5%), farmyard manure (20 t FYM ha-1) and zinc (25 mg Zn kg-1) were added. The treated soil samples were incubated at 35 °C for 1, 45 and 90 days at field capacity and submerged soil moisture regimes. Available Ni was extracted with 0.005 M DTPA extractant and determined by ICP-AES. The results revealed that there was a temporal decrease in the available Ni with ageing and was in the order of 1 day > 45 days > 90 days. The magnitude of decrease in Ni availability was higher with the addition of amendments in the order of lime > FYM > Zn > unamended soil. The decrease in available Ni was further pronounced under submerged moisture regime than under field capacity. The mean per cent recovery of DTPA-Ni in the 10 mg Ni kg-1 spiked treatment decreased from 57.6 after 1 day of incubation to 29.3 and 26.8 after 45 and 90 days of incubation, respectively; whereas in the 25 mg Ni kg-1 spiked soil, per cent recovery of Ni decreased from 60.0 after 1 day of incubation to 29.0 and 25.1 after 45 and 90 days of incubation, respectively. An overall reduction in the mean per cent recovery of DTPA-Ni was observed under submergence as compared to field capacity moisture regime in lime, FYM, Zn amended soils and unamended soil. The results enable us to understand the effect of ageing coupled with different amendments under various moisture regimes on Ni availability and provide useful information to work out the capacity of the soil to serve as a sink for Ni.","PeriodicalId":17302,"journal":{"name":"Journal of the Indian Society of Soil Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49310364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been a regular increase in the irrigated area in the country in the last decade that led to a higher yield potential. If poor quality of irrigation water is used it results in decreased yield. So there is a need to assess quality of the irrigation water before its use on the crops. An attempt was made to assess the ground water quality of different villages in Chikkamagalur block of Chikkamagalur district in Karnataka using various water quality parameters. The values of pH ranged from 6.3 to 8.0, while electrical conductivity ranged from 0.10 to 1.10 dS m-1. Sodium and potassium content in the irrigation water ranged from 0.13 to 3.83 and 0.10 to 5.12 meq L-1, respectively. Calcium and magnesium contents which indicate the hardness of the water and are the important cations was recorded between 0.60 and 5.85 meq L-1. Chloride concentration varied from 4.40 to 11.2 meq L-1, while bicarbonate ranged from 0.4 to 8.8 meq L-1. Based on irrigation water quality index (IWQI), it was found that 87.5% of the water samples of the study area was poor in quality and slightly unsustainable for irrigation, while 8.3% was very poor and only ~4.2% was good in quality for irrigation.","PeriodicalId":17302,"journal":{"name":"Journal of the Indian Society of Soil Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46502601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Application of recommended dose of fertilizers (RDF) along with microbial consortium (PGPR+Actino+Arthro) recorded significantly higher amounts of available nitrogen (N), phosphorus (P) and potassium (K) which resulted in 43, 30 and 37 per cent, respectively over that of fertilized uninoculated control. Similarly, plots receiving RDF+PGPR+Actino+Arthro recorded significantly higher populations of Actinomycetes, Arthrobacter and PGPR at 25, 45 and 65 days after sowing which were 1.71, 1.42 and 1.52 log fold; 1.32, 1.28 and 1.31 log fold; and 1.56, 1.35 and 1.44 log fold, respectively over that of fertilized uninoculated control.
