“…Soil types are considered an important factor that affect the response of P fractions to PAB. The composition of P fractions among soil is related to predominant mineral constituents or the size of particles, as well as the degree of soil cultivation [ 15 ]. To date, the sweet corn was widely cultivation in acidic red soil; however, there has been no detailed quantitative investigation of the changes in the composition of different P fractions with P accumulation in acidic red soil.…”

Excess phosphorus (P) accumulation in the soil can change the bioavailability of P and increase the leaching risks, but the quantitative evaluation of these responses in acidic red soil is lacking. This study aimed to investigate the composition of soil P fractions under different phosphorus apparent balances (PAB) in acidic red soil and the bioavailability and the leaching change-points of different P fractions. Five phosphorus (P) fertilization rates were applied (0, 16.38, 32.75, 65.50, 131.00 kg P·ha−1) in every sweet corn cultivation from the field experiment, and the treatments were marked as P0, P1, P2, P3, and P4, respectively. The PAB showed negative values in P0 and P1 which were −49.0 and −15.0 kg P·ha–1 in two years, respectively. In contrast, PAB in P2 as well as in P3 and P4 were positive, the content ranging from 40.2 to 424.3 kg P·ha−1 in two years. Per 100 kg ha−1 P accumulate in the soil, the total P increased by 44.36 and 10.41 mg kg−1 in the surface (0–20 cm) and subsurface (20–40 cm) soil, respectively. The content of inorganic P fractions, including solution phosphate (Sol-P), aluminum phosphate (Al-P), iron phosphate (Fe-P), reduction phosphate (Red-P), and calcium phosphate (Ca-P), significantly increased by 0.25, 16.22, 22.08, 2.04, and 5.08 mg kg−1, respectively, in surface soil per 100 kg ha−1 P accumulated in the soil. Path analysis showed that the most important soil P fractions contributing to Olsen-P were Sol-P and Al-P, which can directly affect Olsen-P, and their coefficients were 0.24 and 0.73, respectively. Furthermore, the incubation experiments were conducted in the laboratory to investigate the leaching risk of different P fractions, and they showed Sol-P was a potential source of leaching, and the leaching change-points of Al-P and Fe-P were 74.70 and 78.34 mg·kg–1, respectively. Continuous P that accumulated in soil changed the composition of P fractions, and the bioavailability as well as the leaching risks increased. This is important in optimizing soil P fertilization management in agricultural ecosystems based on the bioavailability and critical levels for leaching of P fractions.

“…The presence of trees can increase the soil's infiltration capacity, thereby decreasing run-off and reducing the potential of erosion [24]. The contribution of organic matter from litter has the ability to increase soil porosity and soil permeability [25]. Tree roots can help break down compacted soil, thereby increasing the soil's infiltration [26].…”

This study aims to determine the potential and limitations of land in Ngawi District, East Java, Indonesia, for cultivating rice, corn, and soybeans. The research consists of a four-stage field study conducted in Ngawi Regency: (1) organization of land units; (2) determination of observation points through stratified proportional sampling for each land unit; (3) field surveys; and (4) laboratory analysis. The land evaluation was conducted in accordance with the FAO Guidelines for Land Evaluation for Rainfed Agriculture. The results of the research indicate that 46,417.7 ha (88.1%) of the land area is highly suitable (S1) for rice and 49,286.6 ha (72.1%) is marginally suitable (S3) for corn due to poor drainage. Approximately 62,499 ha (91.4% of the total land area) are marginally suitable (S3) for soybean cultivation. There were suggested five models of land management: (1) intensive rice farming; (2) a relay cropping system for rice-corn or rice-soybeans; (3) multiple cropping systems for corn, soybeans, or rice; (4) a mono-cultural system for rice, corn, or soybeans; and (5) an agroforestry system for Albizia chinensis, corn, and soybeans. Farmers’ awareness of organic management is crucial for enhancing land productivity and maintaining soil fertility in Ngawi Regency.

“…Murphy (2015) states that organic fertilizers can improve soil physical properties at a depth of 10-20 cm. Organic matter can improve soil physical properties such as increasing aggregate stability, increasing soil porosity and permeability (Soelaeman and Haryati, 2012;Prasetyo et al, 2014;Sanjaya et al, 2016;Surya, 2017). According to Minardi et al (2012), provision of organic material is also able to increase soil fertility in degraded land.…”

This study aimed to determine the status of soil damage in Pitu District, Ngawi Regency. The study was conducted in a descriptive exploratory with survey methods. Determination of site sampling was done by purposive sampling, based on distribution or division and land use categories from the results of map overlays. Assessment of soil degradation potency was based on land units from the uniformity of the soil, rainfall, slope, and land use map. Land units resulting from overlay were scored based on the results of multiplication of weights and soil, slope, rainfall, and land use ratings. Total score indicates soil Degradation Potency (SDP). Assessment of soil degradation status was done through matching and scoring. Field observation results were matched with the standard criteria of soil degradation from Indonesian Government Regulation No. 150 of 2000. Each parameter was scored, then the total score was used to determine soil degradation status. Soil degradation potency in
