Assessment of Soil Fertility Status of Radaur Block of Yamunanagar District of Haryana for Better Fertilizer Management

The present investigation was carried out to assess the fertility status of the soils of Radaur Block in Yamunanagar, Haryana. The results presented are compiled using the soil test report of two hundred thirteen soil samples collected from 0-15 cm depth by the farmers of Radaur during 2021-22 and bought to Regional Soil Testing Laboratory, CCS HAU, KVK, Karnal for analysis. The observed data revealed that pH of almost 99.53% soil samples were near neutral ranging between 7.1- 8.0. This pH range is very much appropriate for the availability of majority of plant nutrients. Likewise 96.71% soil samples exhibited EC in very low range making the soil very much suitable for agricultural activities. About 8.45 and 29.11% of Radaur block were found deficient in OC and available K content, respectively. OC status of the soil depicts that 83.09% soil samples were in medium range of OC content and only 8.45% samples exhibited high OC content. As far as P availability is concerned nearly 74% of the soil samples were having available P in high range clearly indicating the buildup of P in Radaur soils. Although none of the sample was found deficient in available P content. Contrary to K status of Yamunanagar soils in 2010-11, in 2021-22 exactly 10 years later the scenario has completely changed and a continuous decline in available K status is exhibited. This decline may be due to low rate of K application through fertilizer and manures with K removal by crops exceeding the replenishment. The results revealed that only 9.39% soil samples were in high range and 61.50% in medium range of K availability.

Comparative Assessment of Soil Fertility Status of Aged and Abandoned Rumuolumeni Dumpsite, Port Harcourt, Nigeria

The levels of pH and soil organic parameters around a solid waste dumpsite receiving untreated wastes from several sources though abandoned for over 10 years and a control site within Rumuolumeni, Port Harcourt, Nigeria was assessed. The top soil of depth, 0–15cm was collected and analysed for pH and alkalinity values, conductivity, total nitrogen, moisture content, total organic carbon (TOC), total organic matter (TOM), and available phosphorus using standard methods. The results were; pH (2.62±0.00 -6.52±0.00), electrical conductivity, EC, µS/) (850±4.95 -1088±1.00), % moisture content (21.51±0.00 -24.74±0.00), % total organic carbon, TOC (2.22±0.02 -3.68±0.02), % total organic matter, TOM (3.396±0.00 -6.393±0.00), % total nitrogen (0.110±0.00 -0.186±0.00), % Phosphorus (1.360±0.00 -2.216±0.00) and alkalinity, mg/kg as 3.816±0.00 -8.15±0.00). The results showed that the waste dump contributed to the high levels of nutrients and heavy metals. The % spatial variation showed pH, % moisture content, TOC, % total nitrogen, % P above 90% for station A while  Conductivity, % moisture content, TOM for station B and conductivity, % moisture content and TOM for station C were also above 90%. The % variation from the control also indicate that station B for pH, TOC and alkalinity were above 90 % whereas in station A, only % total nitrogen (7.46%) and B (5.46%) were below 10 %. This is an indication of depletion in % nitrogen and the pH, alkalinity of the study soil is of toxic level for good soil fertility. The ANOVA result showed that there was no significant difference in the spatial fertility level for the organic parameters (P<0.05). There is need to control planting on this soil locations due to the acidic levels and organic matter contents which have been affected by age, leaching and demineralization processes.

The Soil colour (Dry Condition) of soil varied from Brown, Dark brown, Yellowish brown, Yellowish red, Dark greyish brown, very dark brown and Brownish yellow. Soil colour (Wet Condition) of the soil varied Brown, Dark brown, Yellowish red, very dark greyish brown, very dark brown and Brownish yellow colour. Soil textural classes were sandy loam. It clearly indicated that soil has good Water Holding Capacity (54.19 to 61.80 %) and good physical condition, Bulk Density (0.938Mg m-3 to 1.365Mg m-3). Particle Density (2.124 Mg m-3 to 2.866 Mg m-3). Pore Space (50.018 % to 64.321%). The pH of soil is acidic nature (5.517 to 6.687) and the Electrical Conductivity (0.121 to 0.229 dSm-1) was suitable for all crops. Organic carbon ranged from medium to high (0.902 to 1.182 %). These soils have low Nitrogen (127 kg ha-1 to 252 kg ha-1) in all villages. Phosphorus (18 kg ha-1 to 34 kg ha-1) content is high at eight locations and medium at one location. Potassium (131.8 kg ha-1 to 383.9 kg ha-1) is low in one location and high in two locations. Calcium (5.9 cmol (p+) kg-1 to 8.6cmol (p+) kg-1) and Magnesium (1.2 cmol (p+) kg-1 to 9.8 cmol (p+) kg-1) are very sufficient in this soil. Sulphur (17 Mg kg-1 to 30.5 Mg kg-1) is high in five locations. Zinc (0.79 Mg kg-1 to 0.81 Mg kg-1) content is sufficient in this soil. There is an including awareness of the need to pay greater attention in the role of macronutrients enhancement pin the soil for good soil health and proper nutrition of plant so as to attain optimum economic yield and soil is suitable for all major tropical and sub-tropical crops.

Assessment of soil fertility status in cotton-based cropping systems in Cote d’Ivoire

Cotton is the main cash crop in northern Côte d’Ivoire, where intensive cultivation along with low external inputs has led to a decline in crop yields due to soil degradation. The present study aims to assess the evolution of soil fertility during the 2013 and 2021 periods in the cotton basin area of Côte d’Ivoire. More specifically, the study (i) identified the limiting physico-chemical parameters of soil fertility, and (ii) analysed the state of evolution of soil fertility in 2013 and 2021 in the cotton basin of Côte d’Ivoire. For this purpose, a total of 64 soil samples were taken in 2013 and in 2021 on the same cotton plots on the 0-20 cm horizon. Chemical analyses of the soil samples in the laboratory were carried out on the following parameters: particle size distribution, pH water, total nitrogen (NT), Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+) and Cation exchange capacity (CEC). The results of the soil analyses showed that the sandy-clay textured topsoils dominate the whole study area in both years. This leads to a low retention capacity of exchangeable bases. Determination of the soil pH showed that the pH varies from slightly acidic to neutral (6.5<pH<7). The most limiting chemical properties are Cation exchange capacity (CEC) and the sum of the exchangeable bases (SEB) in the department of Korogho, Boundiali, and Ferkessedougou and the most limiting chemical properties in the department of Mankono are CEC. However, during the period from 2013 to 2021 the content of exchangeable cations (Ca2+, Mg2+ and K+) and the base saturation (BS) increased significantly in all the departments, more precisely in the department of Mankono. Although we observed a slight increase in the chemical properties of the soils in 2021 compared to 2013, the values were still below the minimum required threshold. This result implies that the soils have poor physico-chemical properties and consequently a low level of fertility, which compromises the sustainability of the cotton production system. The application of organic and mineral amendments is therefore essential to increase the nutrient content of these soils.

Assessment of Soil Fertility Status under Soil Degradation Rate Using Geomatics in West Nile Delta

The presence of a noticeable rate of degradation in the land of the Nile Delta reduces the efficiency of crop production and hinders supply of the increasing demand of its growing population. For this purpose, knowledge of soil resources and their agricultural potential is important for determining their proper use and appropriate management. Thus, we investigated the state of soil fertility by understanding the effect of the physical and chemical properties of the soil and their impact on the state of land degradation for the years 1985, 2002 (ancillary data), and 2021 (our investigation). The study showed that there are clear changes in the degree of soil salinity as a result of agricultural management, water conditions, and climatic changes. The soil fertility is obtained in four classes: Class one (I) represents soils of a good fertility level with an area of about 39%. Class two (II) includes soils of an average fertility level, on an area of about 7%. Class three (III) includes soils with a poor level of fertility, with an area of about 17%. Class four (IV) includes soils of a very poor level of fertility with an area of about 37% of the total area. Principal component analysis (PCA) has revealed that the parameters that control fertility in the studied soils are: C/N, pH, Ca, CEC, OM, P, and Mg. Agro-pedo-ecological units are important units for making appropriate agricultural decisions in the long term, which contribute to improving soil quality and thus increasing the efficiency of soil fertility processes.

Evaluation of soil fertility: a case study in Aceh Besar district

Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E.
