Fertility Mapping of Available Micronutrients Status in the Soils of Dharmapuri District, Tamil Nadu, Using GIS and GPS Techniques

Abstract

A soil resource inventory was conducted at village level in all the blocks of Dharmapuri district, Tamil Nadu to assess the micronutrients status in the soils and to prepare fertility maps depicting the extent of soil micronutrient deficiency/sufficiency using GIS and GPS techniques. Soil samples were collected at Panchayat village wise along with geo coordinates and analysed for available micronutrients such as Zn, Fe, Cu, Mn and B by adopting standard procedures. Based on the nutrient status, the soils were grouped as deficient or sufficient using the critical limits. Per cent deficiency of micronutrients in each block was worked out and the thematic maps showing status of different available micronutrients were generated at block level. The results indicated that, Zn deficiency is most prevalent in the soils of all the blocks in Dharmapuri to an extent of 67.4 per cent, followed by Cu (7.8 %) and B (6.8 %), where as the other micronutrients were in sufficient level.

A raw data article on the physico-chemical properties of soil from six firkas in Dharmapuri district, Tamil Nadu, India

“…The study area comprises six firkas namely Marandahalli, Vellichandai, Palacode, Karimangalam, Pulikarai, and Periyanahalli are located in the Dharmapuri district ( Fig. 1 ), which covers latitudes between 11˚45’ and 12˚15’N and longitudes between 77˚30’ and 78˚30’E, encompassing approximately 482 km 2 [1] . Regarding the climate, the hottest period of the study area was March to May, with maximum temperature of 38˚C and minimum temperature is about 17˚C which was recorded in January.…”

Soil: Chemical characteristics of Vallanadu series in Tamiraparani river basin of southern Tamil Nadu, India

“…The higher manganese content in the surface soil was related to the acidic nature of the soil. The lower amount of zinc and copper might be attributed to the acidic pH, texture and fixation with the clay (Jegadeeswari et al, 2017) [5] .…”

Spatial Variability of Soil Chemical Properties in Patna, Vaishali and Saran Districts Adjoining the Ganga River, Bihar, India

“…The use of GPS devices can improve the quality and future applicability of that data for various purposes. Study of soil fertility status and mapping of pH, electrical conductivity, organic carbon, nitrogen, phosphorus, potassium, sulphur, zinc, iron, copper and manganese using GIS interface were reported from several localities (Arunkumar et al, 2016;Kumar et al, 2017;Santhi et al, 2018). Thus, the geostatistical tools are getting much more effective in soil health management.…”
