“…Soil amendment (ameliorant) provides benefits in reducing damage, securing nutrients in the soil, and helping microbial symbiosis (Ahn et al, 2022). Microorganisms in soil require renewable organic material for enzyme activity which is closely related to soil microbial populations and soil fertility (Chen et al, 2024). The application of bio-organic ameliorants to soil has a positive impact on environmental stress conditions by reducing dissolved salt content and sodium levels in the soil, as well as improving soil fertility containing high levels of salinity and acidity (Hafez et al, 2022).…”

Soil fertility affects the diversity and quality of soil microbes in decomposing organic matter and recycling nutrients. Inceptisols soil is young soil that is starting to develop with its soil fertility status. Management is needed to maximize sustainable soil quality and high plant productivity. Chili plants are widely cultivated but suboptimal soil conditions can inhibit plant growth. Ameliorant materials can be organic or inorganic materials. Ameliorant provides benefits in reducing damage, maintaining nutrients in the soil, increasing the organic nutrient content in the soil and helping microbial symbiosis. The efficiency of nutrient use depends on the plant's ability to absorb nutrients. The effectiveness of nutrient management strategies by combining inorganic and organic nutrient inputs, it is proven that balanced nutrient management can increase plant growth and productivity. Ameliorant can come from organic and inorganic materials which can increase soil fertility from biological and chemical properties, the productivity of chili plants. The materials used as ameliorant are biochar, biosolids, animal waste, microalgae. When cultivating chilies in inceptisol media, it is necessary to apply ameliorant combined with effective essential nutrients, in order to increase chili productivity and contribute to agricultural agriculture.

“…Previous studies have shown that there was indeed some association between soil nutrients and soil quality [20,21]. Soil nutrients and soil organic matter (SOM) are soil indicators that directly affect crop growth [22][23][24]. Therefore, they can be used to reflect the changes in soil quality.…”

Drip irrigation is an effective method to utilize waste saline-sodic land with a high water table. For reasonable and sustainable utilization of saline-sodic soil under such conditions, spatiotemporal changes in total nitrogen (TN), total phosphorus (TP), and soil organic matter (SOM) were investigated during the utilization process. The soil was sampled from newly built raised beds before planting (0 y) and beds in three adjacent plots had been planted with Lycium barbarum L. for one (1 y), two (2 y), and three years (3 y), respectively, at the end of the growing season. Soil samples were obtained at four horizontal distances from the drip line (0, 10, 20, and 30 cm) and four vertical soil depths (0–10, 10–20, 20–30, and 30–40 cm). The results showed that the average TN and TP of the soil profile increased with the planting year and were approximately 0.68 and 1.81 g·kg−1 in the soils of 3 y, approximately 84.9 and 42.4% higher than that of 0 y, respectively. SOM decreased in the first growing season and then continuously increased in the following planting years, reaching 8.26 g·kg−1 in the soils of 3 y, which was approximately 38.2% higher than that of 0 y. TN, TP, and SOM contents were high in soils around the drip line and decreased with distance from the drip line. In both horizontal and vertical directions, TN, TP, and SOM varied slightly in soils of 0, 1, and 2 y, while in soils of 3 y, TN and SOM decreased with increased distance in both horizontal and vertical directions and TP decreased obviously only within 10 cm in both directions. This indicated that the contents and distributions of soil nutrients in such saline-sodic soils could be improved with planting year under drip irrigation with local saline groundwater and especially around the drip line as the soil around the dripper was quickly ameliorated.
