Soil Fertility Status

Soil fertility management in agricultural land is challenging in hilly areas of Nepal. The study assesses the soil fertility status of Bari (upland) and Khet (lowland) agriculture land in Mid-hill of Gorkha district. Altogether 30 samples were collected from soil surface (0 to 20 cm) by using hand shovel in January, 2017. The soil fertility parameters like pH, organic matter (OM), total nitrogen (TN), available phosphorus (P) and available potassium (K) were analyzed using standard methods in the laboratory of Central Department of Environmental Science, Tribhuvan University. Results revealed that an average pH in upland (6.62) was higher than the lowland (5.94). Similarly, OM (3.95%) and K (36.49 kgha-1) were relatively high in upland. In addition, pH, OM and available K were significantly varied at p<0.05 in upland and lowland soils, however, there is no significant difference in TN and available P. In addition, soil nutrient index showed that status of available K in both types of land is low, while OM and TN are medium soil quality in upland and lowland soil. The use of organic fertilizer and improved farming system can maintain and sustain soil fertility for crop growth and yield. Understanding distribution of soil nutrients in the study area might be useful for planners to make effective soil fertilizer management strategies.

A 15- year (1993-2007) long-term integrated soil fertility management (ISFM) study on coconut (‘Laguna’ tall variety) + lanzones fruit tree (‘Paete’ variety) agro-ecosystem was conducted using five fertilizer combinations (FCs) in a dominantly tropical wet climate growing zone (Koppen-Geiger Climate Classification, Kottek et al 2006) of Davao, Southern Mindanao, Philippines (07o05’N 125o37’E. One of the objectives of the study was to determine the response of this agro-ecosystem to the combined application of inorganic multinutrient fertilizer (MNF): N+P+K+Cl+S+B (14% N-5% P2O5-20% K2O, with 15.5% Cl, 4.5% S and 0.02% B) and organic fertilizer sources at different ratios by weight by tree (IF+OF at 1+0; 1+2; 2+4; 4+2 and 4+4) on: crop productivity; soil properties, and leaf nutrient levels of the agro-ecosystem. The influence of ISFM and MNF on yields and profitability of the agro-ecoystem coconut and lanzones fruit tree crop (Part I) had been presented earlier in the CORD J. (Magat et al 2009) Results as presented in the first part of the work report showed that the application of the multi-nutrient inorganic fertilizer even at its lowest rate for coconut (1 kg/tree/yr) produced a significant increase in annual nut and copra yield per ha from an average of 8,890 nuts or 1.6 tons to 3 - 4 tons after 2 years of fertilizer applications. The non-significant difference in nut and copra yields of fertilizer combinations (FCs) in almost all years showed that even with the application of FC-1 (1 kg of inorganic fertilizer), the lowest rate of the multi-nutrient fertilizer, even without organic fertilizer, an annual yield over 4 tons copra per ha (or over 17, 000 nuts per ha) was produced in most of years of production, seldom achieved in coconut farms in the country. The improvement of coconut yield and very productive lanzones fruiting stage in this cropping system may be attributed to the significant influence of fertilizer combinations on the crops’ leaf nutrient contents as N, P, K, Cl and B. The long term effect of organic fertilization contributed much to the improved or enhanced soil physical conditions as the soil bulk density. Soil chemical properties as soil acidity, organic carbon (C), organic matter, available phosphorus (P) and exchangeable potassium (K) were generally enhanced during the 15 years of coconut and lanzones cropping under ISFM with multi-nutrient fertilizer application. This long-term coconut + lanzones cropping agro-ecosystem proved to be a sustainable farming system. The proper integrated soil fertility management (ISFM) as a major component of the integrated crop management (ICM) using the PCA-formulated crop-specific-fertilizer multi-nutrient 14(N)-5(P2O5)-20(K2O)-15.5(Cl)-4.5(S)-0.02(B) even at the lowest rate of fertilization contributed to stable soils resulting to the total productivity of the coconut + lanzones fruit tree agro-ecosystem.

Rice is a staple food for the Indonesian people and is a national strategic commodity for national food security. Rainfed area is a potential land to support national rice production, by improving soil management through balanced fertilization based on the soil characteristics. This study aims to determine the soil fertility and alternative management implemented in 2019 and 2020 in Sukaraja and Pondok Kelapa sub districts, Bengkulu Province. Soil fertility status for CEC, base saturation, C-organic, total P and total K taken based on the classification of the value of the combination of these chemical properties. The results showed that the soil fertility status of the rainfed rice fields in Sukaraja and Pondok Kelapa sub districts was low. The limiting factors for soil fertility for Sukaraja sub district are alkaline saturation, total K-total and P-total for Pondok Kelapa sub district. The limiting factors are all elements related to nutrient status assessment, namely CEC, base saturation, total P, total K and C-organic. Alternative soil management is carried out in an integrated manner by providing balanced organic and inorganic fertilizers. The provision of soil amendments such as straw compost, manure, biochar and agricultural lime/dolomite, especially for acid reacting soils, aims at increasing soil fertility before fertilization is applied.

Field studies were conducted at farmer’s fields in Jodalli (Kalghatgi taluk) and Pale (Hubballi taluk) villages in 2012-13 and 2013-14, respectively to investigate the effect of NPK fertilizers on uptake of nutrients by Bt cotton and soil fertility status at harvest in Alfisol. Among the different treatment combinations, the application of 150:50:75 kg N:P2O5:K2O ha-1 (N3P1K2) recorded significantly (P=0.05) higher nitrogen (132.63 kg ha-1), phosphorus (31.26 kg ha-1) and potassium (128.94 kg ha-1) uptake by cotton. The interaction effect with respect to total micronutrients (Zn, Fe, Mn and Cu) uptake remained non significant at all the growth stages. Graded levels of fertilizers failed to exert significant impact on pH and electrical conductivity, soil organic carbon and available micronutrients during both the years of experimentation. The application of 100:50:50 kgN:P2O5:K2O ha-1 (N1P1K1) recorded significantly (P=0.05) highest available nitrogen (150.39 kg ha-1), available phosphorus (37.98 kg ha-1) and available potassium (230.99 kg ha-1) compared to rest of the treatments. The lowest available nitrogen (134.92 kg ha-1), available phosphorus (31.65 kg ha-1) and available potassium (217.63 kg ha-1) were recorded in treatment receiving 150:50:75 kg N:P2O5:K2O ha-1 (N3P1K2).

Soil test-based fertility management is important for sustainable soil management. This study was carried out to determine the soil fertility status of the Agriculture Research Station, Belachapi, Dhanusha, Nepal. Using soil sampling auger 25 soil samples were collected randomly from a depth of 0-20 cm. Soil sampling points were identified using GPS device. Following standard methods adopted by Soil Science Division laboratory, Khumaltar, the collected soil samples were analyzed to find out their texture, pH, N, P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu, Mn and organic matter status. The soil fertility status maps were made using Arc-GIS 10.1 software. The observed data revealed that soil was grayish brown in colour and sub-angular blocky in structure. The sand, silt and clay content were 36.03±3.66%, 50.32±2.52% and 25.42±2.25%, respectively and categorized as eight different classes of texture. The soil was acidic in pH (5.61±0.14). The available sulphur (0.73±0.09 ppm) status was very low, whereas organic matter (1.34±0.07%), available boron (0.56±0.10 ppm), available zinc (0.54±0.22 ppm) and available copper (0.30±0.01 ppm) were low in status. The extractable potassium (95.52±13.37 ppm) and extractable calcium (1264.8±92.80ppm) exhibited medium in status. In addition, available phosphorus (33.25±6.97 ppm), available magnesium (223.20±23.65 ppm) and available manganese (20.50±2.43 ppm) were high in status. Furthermore, available iron (55.80±8.89 ppm) status was very high. To improve the potentiality of crops (maize, rice, wheat etc.) for studied area, future research strategy should be made based on its soil fertility status.

A study was conducted in the rice zone of Morang district to examine soil fertility status and the most limiting nutrient in the research area in accordance with rice cultivation requirements. Hundred samples were collected from two different locations of Ratuwamai Municipality ward number 6 and 8 at depth of 0-15 cm from surface soil. Samples were analyzed to find texture, pH, Nitrogen, Phosphorus, Potassium and Soil Organic Matter (SOM). Statistical tools were used to analyze the data. The most limiting nutrient in rice fields were determined by comparing the observed value with the standard requirement for rice fields. From analysis, it was revealed that, nitrogen content was found medium. Phosphorus was low in ward 6 whereas medium in ward 8. Potassium was high in ward 8 whereas medium in ward 6. SOM was low due to less application of organic fertilizer. Majority sample were of acidic probably due to more use of urea. Thirty percent samples of ward 8 were neutral and with equal alkalinity in both wards. Majority of sample was sandy loam except in ward 8 where ten percent sample was clayey loam. Both wards show equal behavior of loamy soil. Nutshell, majority of samples were of low fertility. Nitrogen and Potassium was most limiting as per the rice cultivation requirement with optimum soil pH. Various extension works regarding the importance of soil fertility management, sustainable soil management, optimum application of organic and inorganic fertilizers and the techniques to enhance the soil fertility status is required.

Soil fertility assessment is a key for sustainable planning of a particular area. Thus, the present study was conducted to assess the soil fertility status of the Regional Agricultural Research Station, Parwanipur, Bara, Nepal. The study area is situated at the latitude 27°4’40.9’’N and longitude 84°56’9.85”E at 75masl altitude. Altogether 76 soil samples were collected based on the variability of land at 0-20 cm depth. The texture, pH, OM, total N, available P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu and Mn content in the samples were determined following standard analytical methods. Arc-GIS 10.1 was used for soil fertility mapping. The soil structure was angular blocky, and varied between grayish brown (10YR 5/2) and dark grayish brown (10YR 4/2) in color. The sand, silt and clay content were 24.41±0.59%, 54.57±0.44% and 21.03±0.32%, respectively and categorized as silt loam and loam in texture. The soil was moderately acidic in pH (5.67±0.09), low in organic matter (0.74±0.04%) and available Sulphur (0.8± 0.1 ppm). The total nitrogen (0.06±0.001%), available boron (0.59±0.08ppm) and available zinc (0.51±0.05ppm) were low. Furthermore, available potassium (50.26±2.95ppm), available calcium (1674.6±46.3ppm) and available magnesium (175.43± 8.93ppm) were medium. Moreover, available copper (1.36±0.06 ppm) and available manganese (16.52±1.12 ppm) were high, while, available phosphorus (77.55±6.65 ppm) and available iron (85.88±7.05 ppm) were found high. It is expected that the present study would help to guide practices required for sustainable soil fertility management and developing future agricultural research strategy in the farm.
