Abstract

This research was carried out in Laut Tador Village, Sei Suka District, Batu Bara Regency, North Sumatra Province. This place is at an altitude of ±25 meters above sea level (masl), with flat topography. This research was carried out from November 2021 to February 2022. This research aims to determine the dose of inorganic fertilizer and types of manure on N, P and K nutrient uptake and on the growth of soybean plants (Glycine max). This research began in October 2021 to February 2022. Factorial pattern research with a factorial Randomized Block Design/RAK. Treatment factors use various types of manure (O) as the first factor and the second factor is the application of inorganic fertilizer (A). The results of soil analysis on the experimental land are generally low, indicated by the organic matter content at the location, namely 0.25%, not reaching 3% according to ideal soil conditions. . Research Results: The type of manure treatment had a significant effect on the number of primary branches, plant height, stem diameter, crown dry weight, number of root nodules, root nodule weight, while the interaction of organic and anoragnic fertilizers had no significant effect on the number of primary branches, plant height and nutrient uptake. . Providing chicken manure at a dose of 15 tons ha produced the highest number of primary branches, plant height, stem diameter, crown dry weight, number of root nodules, and root nodule weight.

Abstract

The increase in national corn demand has triggered the utilisation of marginal land, including riverbank areas. This study aims to identify soil characteristics and evaluate land suitability for corn (Zea mays L.) cultivation in the Alas River border area, Southeast Aceh Regency. The research method used is descriptive exploratory with field surveys through pedon (soil profile) creation and laboratory analysis of soil physical and chemical properties. Morphological observations showed soil profiles developed from fluvial sedimentation material with A1, A2, C, and R horizons. Based on USDA Soil Taxonomy, the soil at the study site was classified into the Entisol order, Psamments suborder, and Udipsamments great group, dominated by sand fractions (78.42%–89.30%). Chemical analysis results show that the soil has an acidic pH (4.53–4.86), very low organic carbon content (0.15%–0.71%), and low cation exchange capacity. Based on the matching method, the land suitability class for maize cultivation is determined as N1 (currently unsuitable) with the main limiting factors being shallow effective depth (30 cm), very sandy soil texture, acidic pH, and low organic matter content. However, land potential can be improved through appropriate management strategies, such as liming to raise pH and adding organic fertiliser to increase water and nutrient retention capacity.
