“…Mineralization (N supply) and immobilization (N removal from the mineral N pool) (M&I) are highly dependent on the soil organic matter (OM) and the amount of clay in a soil. Soils with less than 3% of OM in the upper horizon, as in our study, are classified as mineral soils (Huang et al, 2009), in which the M&I processes are often limited due to the lack of OMs (Wijanarko, 2015;Deenik, 2006;Herrmann, 2003;Li et al, 2003). Moreover, mineralization tends to be greater in coarsetextured soils with the low clay content and smaller as the soil clay content increases.…”

a b s t r a c tNitrate losses are the dominant cause of the non-point source pollution under agricultural fields. In this study, the HYDRUS-2D model was first calibrated and validated using data collected during a two-year field investigation in a drip-irrigated maize field and then applied to evaluate the influence of 176 different N-managed water-saving irrigation scenarios on water and N dynamics and maize grain yield. Various scenarios were defined by combining 11 irrigation levels (IL = 0-100% with a 10% interval), 8 N fertilization rates (NR = 0-400 kg ha −1 with a 50 kg ha −1 interval) and two water-saving irrigation strategies: deficit irrigation (DI) and partial root-zone drying (PRD). Reliable estimates of soil NO 3 − -N concentrations (RMSE = 0.39-10.9 mg l −1 and MBE = −8.9-8.4 mg l −1 ), crop N uptake (RMSE = 3.9-8.9 kg ha −1 and MBE = −5.3-6.25 kg ha −1 ), and soil water contents (RMSE = 2.3-5.11 mm and MBE = 1.63-4.93 mm) were provided by HYDRUS-2D. Based on the simulated results, the fertigation strategy with NR = 200 kg ha −1 is an optimum strategy. For the higher fertigation rates (NR ≥ 250 kg ha −1 ), the NO 3 − -N leaching out of the surface layers (0-20 cm) increased by 0.1-183% while N uptake was enhanced by only 0.3-15%. On the other hand, reducing NR below this level would have resulted in severe economic losses. A 30% reduction in IL at NR = 200 kg ha −1 shows an enormous potential in lowering N leaching below different soil layers (12-99%) while reducing crop N uptake by only 5.4%. In addition, higher crop yield by 0.2-20.2% can be expected under PRD since crop N uptake is enhanced by more water available in the surface layers. While on the one hand, PRD ensures environmentally safer fertilizer applications, on the other hand, the economic objectives are met more easily under PRD than under DI. Additionally, it could be concluded that the HYDRUS-2D model, instead of labor-and time-consuming and expensive field investigations, could be reliably used for determining the optimal scenarios under both the DI and PRD strategies.

“…Aside from inorganic fertilizer, organic fertilizer could contribute nutrients like N from plant biomass. Organic matter also had an important role in increased microorganism activity to transform organic N into inorganic N [17]. With the result of that, combination of compost and N, P, K, S fertilizer could generate shallots dry bulbs weight better than control and utilization of N, P, K, S fertilizer only.…”

“…Organic matter could hold water and nutrients so prevented them from leached easily. The amount of organic matter in soil determines soil capability to provided N nutrient that was produced from the decomposition of biomass [17]. Furthermore, organic matter could increase soil cation exchange capacity (CEC) so N exchange on cation and anion form would be increased [9].…”

“…Nutrient uptake by plants depends on the concentration of nutrients in the soil. The concentration of nutrients in the soil is affected by the rate of mineralization (Wijanarko et al, 2012). Nitrogen uptake is a parameter of the amount of nitrogen content in plants which will affect the rate of plant development and growth.…”

Compost fertilizer is very influential on the nutrient status of the soil and plants. Giving compost fertilizer will also have a good effect on the growth and development of mustard plants. This study aims to determine the effect of the addition of biostarter on compost fertilizer to N-total and N nutrient absorption on mustard plants. The experiment was structured using factorial randomized group design. The method in this study using compost analysis,soil analysis, and plant analysis. The results showed that the nine samples have different nutrient content and nutrient nutrient absorption resulting in different effects on soil and mustard plants. Nitrogen in the soil greatly affects the N nutrient absorption on plants, the two parameters have a positive correlation which means directly proportional. Nitrogen absorbed by plants affects N-total levels in plants. N levels in plants and soil is very influential on the color of the leaves of mustard plants. Through the nutrient levels can be known proper fertilization recommendations for mustard plants. Based on the analysis of nutrient levels in soil and plants known fertilizer recommendations in nine samples with the addition of biostarter in kudzu compost and fertilizer doses.
