Nine typical pedons from Langate Block of Kupwara district during 2017 were selected and surveyed for the purpose of collection of soil samples. The soil samples processed and analyzed for different nutrients. Available Micro and Macro nutrients were determined using standard techniques. The overall results showed that the soils are near slightly acidic to moderate alkaline in reaction, low to medium in organic carbon. In general the soils The available nutrients Nitrogen and Potassium were low to medium with the mean values of 287.99 and 149.

The representative soil series of order Entisols, Inceptisols and Vertisols collected from agriculture college Kolhapur and different research stations of Sub-montane zone of Maharashtra were assessed for different forms of potassium and its distribution. The water soluble K contributed very lowest fraction than the rest of all forms of potassium (i.e. 0.23 % of total K). From the mean values higher water soluble K was noticed in Vertisols followed by Inceptisols and Entisols.

An investigation was carried out to study the distribution of available macronutrients (N, P, K and S) and their relationship with some physico-chemical properties of soil of different blocks of district Udham Singh Nagar (Uttarakhand).The soils of the district were found sufficient in Phosphorus, Potassium and Sulphur but low in available Nitrogen content. In general the macronutrients were correlated significantly and negatively with pH and positively with organic carbon of the soil.

The present study revealed that pH of pear orchard soils increased with decrease in altitude while as organic carbon decreased with decrease in altitude. The textural class of soils ranged between clay loam to silt clay loam with normal electrical conductivity. The available nitrogen status was low to medium, whereas, available phosphorus status was medium to high and available potassium status was high.

GPS based total 150 surface soil samples (0-15 cm) were collected from each block (30 samples) (namely; Mungaoli, Chanderi, Ishagarh, Ashoknagar and Sadora) of Ashok Nagar district. The samples were prepared and analyzed for different soil properties viz: soil texture (sand silt and clay), pH, EC, soil organic carbon (SOC), Calcium carbonate different forms of potassium (i.e., water soluble, exchangeable, non- exchangeable lattice and total-K) used standard laboratory method.

Among the various Sub-catchments in the state of Jammu and Kashmir, the Namblan Subcatchment of Jhelum basin has not been studied in view of the nutrient status of the soils. Based on variations in vegetation, altitude, land use and soil heterogeneity six representative soil profiles were exposed and studied for their depth wise distribution of Nutrient. Soil samples collected thereof, were analyzed for various macro and micro nutrients. While as the increasing trend was followed by the macro-nutrients and micro nutrients. The contents of nitrogen and potassium were in the range of 231.

An investigation was carried out at College of Agriculture, Shivamogga during the year 2016-17 in order to know the status of potassium in soils under arecanut gardens of Davanagere district, Karnataka. For the study, 200 surface and sub-surface samples were collected from soils under arecanut garden of four taluks (Channagiri, Honnali, Harihara and Davanagere) of Davanagere district.

Spatial distribution of nitrogen, phosphorus and potassium were studied from 99 coconut farmers covering 195 acres representing different irrigation situations in Chikkapattanagere of Chikkamagaluru district, Doddaghatta of Davangere district, Siriyur of Shivamogga district and Madhure of Chitradurga district of Karnataka state, India. The gardens selected were aged 20-25 years with varying management levels.

A Study was undertaken to evaluate the fertility status of Nignoti village, Indore district, Madhya Pradesh covering a village during 2013-2014. The systematic collection of samples in geo–referenced surface (0-15cm) soils was done from 250 sites representing Vertisols and associated soils. The samples were analyzed for Mechanical composition of soil viz., Sand, Silt, Clay and chemical composition viz., pH, EC, O.M., and analyzed the different forms of potassium viz., water soluble K, exchangeable K, available non exchangeable K, lattice K, total K.

Surface (0-20) and sub-surface (20-40) soils from six different administrative blocks (Dhuluabari, Pundibari, Toofanganj, Mathabhanga, Dinhata and Sitai) of Cooch Behar district of West Bengal situated in terai region of Himalayan flood plain, India were analyzed to characterize the spatial distribution of different forms of potassium (K). The soils were acidic in nature, mostly sandy loam in texture and variable in organic carbon content and CEC.

The estimation of crop yield before harvest helps in different policy making in an order for storage, distribution, marketing, pricing, import-export etc. Crop productions depend on several factors such as weather factors, plant characters and agricultural inputs. The present study was carried out to develop the appropriate statistical model for estimation of rice yield before harvest in the year 2018-19. This research was done on plant biometrical characters along with farmer’s appraisal.

Laboratory analysis was made on the soil samples collected (October 2013) from an on-going long-term field experiment (in progress since Kharif 2009-10) at Department of Soil Science, PAU, Ludhiana to investigate the effect of manure and chemical fertilizers in rice (Oryza sativa L.) - wheat (Triticum aestivum L.) system. The organic manure through bio gas slurry (BGS) @ 6 t ha-1 was incorporated along with nitrogen fertilizer (N @ 80 and 120 kg ha-1 ), phosphorus fertilizer (P @ 30 kg ha-1 ) and potassium fertilizer (K @ 30 kg ha-1 ) to the rice crop.

Eulophia angolensis is an endangered plant species found in the Okavango Delta. Generally, there is lack of botanical information on this species in Botswana, which is necessary for its in-situ and ex-situ conservation. The objectives of this research are to map areas where E. angolensis occurs, determine the species that co-exist with it, and establish soil factors that influence its abundance and distribution in the Okavango Delta. A survey of the area where the plant was sighted in 2004 was carried out using recorded GPS points.
