Abstract

The physical properties of the soil that need to be considered are the problem of degradation and soil structure due to management functions so that cultivated land is not eroded and organic matter is lost quickly.This research was carried out through 2 stages of activities, namely field activities and analysis activities. Stages of field activities were carried out at the Palm Oil Plantation on the Practical Land of Labuhanbatu University, Labuhanabtu, North Sumatra Province at a height of 28 meters. The method used in this research is a free grid measurement method at a semi-detailed survey level (observation frequency of 1 sample per 500 meters). Carrying out soil sampling at up to 5 sampling points with a distance of 100 meters in the field using a random method, spread over a predetermined area based on the base map. Results of land use research withSoil texture in the Labuhanbatu University Practice Field, Labuhanbatu Regency, sandy loam, The bulk density value shows low, soil porosity is still high, the soil color looks relatively dark, and the soil water content is still relatively normal.

Abstract

The mainstay commodity that can be expected to increase the income and dignity of plantation farmers and Indonesian transmigrants is Palm Oil (Elaeis Guinensis Jacq). Oil palm Soil microbes have an important role in the soil ecosystem which is responsible for the nutrient cycle to maintain soil fertility and structure, especially the biological properties of the soil. This research was carried out through 2 stages of activities, namely field activities and analysis activities. Stages of field activities were carried out at the Kebun Sinar Pandawa Palm Oil Plantation PT. Sinar Pandawa, Labuhanabtu, North Sumatra Province with a height of 28 meters. The method used in this research is a free grid measurement method at a semi-detailed survey level (observation frequency of 1 sample per 500 meters). Carrying out soil sampling at up to 5 sampling points with a distance of 100 meters in the field using a random method, spread over a predetermined area based on the base map. Research Results Land use with different vegetation produces different biological and chemical soil properties. Soil organic C was positively correlated with total microbial population, total fungal population, and respiration. The highest correlation between biological and chemical soil properties was obtained from the total microbial population with a total P of 0.714. The highest correlation was obtained from the correlation between organic C and total N levels, namely 0.947.

The physical properties of the soil that need to be considered are the problems of degradation and soil structure due to management functions. In addition, on cultivated land that is not eroded, organic material is lost quickly.This research was carried out through 2 stages of activities, namely field activities and analysis activities.

Abstract

The Bilah Sub-Watershed area includes areas that have somewhat critical or semi-critical land so that land use is the result of human efforts in managing the available resources to meet their various needs. This often results in land use not being in accordance with its capabilities. This research aims to examine the chemical properties of several vegetation in Negeri Lama Seberang Village, Bilah Hilir District, Labuhanbatu Regency. The research was carried out from December to March 2024 using a survey method. Soil samples were taken at 3 points for each vegetation and different slopes at depths of 1-10 cm and 10-20 cm using a simple random method. The soil parameters measured were soil acidity (electrometry), soil organic carbon content (Walkley and Black), and soil texture (bouyoucos hydrometer). Soil analysis was carried out at the Laboratory of the Faculty of Agriculture, University of North Sumatra. The results of this research show that on a slope of 0-8% the average soil pH value is 4.61% and organic C is 1.04%, while on a slope of 8-15% the average soil pH value is 4.46% and C -organic 0.91%. On a slope of 0-8% the average value of the clay fraction is 20.27%, the dust fraction is 15.02% and the sand fraction is 64.41%, while on a slope of 8-15% the average value of the clay fraction is 27.48%, the dust fraction 19.87%, and sand fraction 52.63%.

Abstract

Evaluation of nutrient availability needs to be carried out to determine the ability of the soil to provide nutrients for plant growth, in this case the evaluation of the nutrient content of paddy fields in three locations in the Balige area, namely Huta Namora, Huta Bulu Mejan and Baruara. This is needed as information for the management of paddy fields on the provision of fertilizers in the future, both inorganic fertilizers and organic fertilizers. The purpose of this study was to evaluate the availability of soil nutrients such as organic C, total P, available P and soil pH after rice harvest. This research is a descriptive study by comparing data from the three research locations. In its implementation, 9 sample points of observation were chosen representing the location of each area. Every 3 sample points were mixed into one point of soil samples from the three research locations showing relatively the same results so that in one location there were 3 points of soil samples which were considered as replication 1, 2 and 3 replications. Thus, there were 9 soil samples for the three research locations. Based on the results of laboratory analysis shows that the nutrient content is relatively the same, namely for organic C content with low to moderate criteria, P-total nutrient content is on average between 6.55-7.52 (%) (low to moderate), for P is available between 27,241 – 28,909 with very low criteria. The pH parameter for paddy fields is relatively the same as the neutral criterion. This information becomes quite expensive information for the management of paddy fields in the future. The suggestion is to reduce the use of inorganic fertilizers and switch to the use of biological fertilizers and organic fertilizers.

Soil samples was analyzed at the Analytical Laboratory of PT Socfindo Indonesia North Sumatera Province. Which began in October to December 2023 The method used is Free Grid Survey semidetailed level survey and analysis of nutrient data total phospate by Acid destruction method (HClO4), available phosphate by Bray II method, soil pH by H2O extraction and organic carbon by walkley & black method and then interpret to the map nutrient status. The result of research showing that status total phosphate classified by 3 status such as, medium (81,59 ha), high (81,15 ha) and very high (27,26 ha). Available phosphate classified in 3 nutrient status such as very low (39,11 ha), low (137,40 ha) and medium (13,49 ha). Soil pH classified in 2 status such as moderately acidic (30,16 ha) and strongly acidic (159,84 ha). Organic carbon classified by 3 nutrient status such as very low (3,06 ha), low (135,84 ha) and medium (51,10 ha). Available phosphate and organik carbon affect rice production in Meijan Village Balige District Toba Regency.
