Abstract
Sandy soil has certain limitations such as low water holding capacity, high infiltration, high evaporation, and low soil moisture. To solve these problems, the addition of mycorrhizae and soil amendments to sandy soil could be able to improve the limitation. This study aimed to determine the effect of mycorrhizae and soil amendments on physical characteristics of sandy soil. The experiments were arranged using the CRD (Complete randomized design) method with two factors: doses of mycorrhizael and types of soil amendments. Doses of mycorrhizae consist of M0 (without mycorrhizae), M1 (mycorrhizae 3 spores pot-1 ), and M2 (mycorrhizae with 6 spores pot-1 ). The types of soil amendments consist of A0 (control), A1 (cow manure), A2 (biochar), A3 (clay soil), A4 (cow manure-biochar), A5 (cow manure-clay soil), A6 (biochar-clay soil). The results showed that mycorrhizae with cow manure-clay soil (M1A6) maintained the average of soil moisture seven days after harvest with an average of 12.65% and also reduced the rate of soil permeability three times than control. The combination of biochar-clay soil and mycorrhizae improved the water holding capacity and soil aggregation. Interaction of mycorrhizae and soil amendments improved the physical characteristics of sandy soil by increasing soil moisture and reducing soil permeability
