Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil compaction indicator can be seen from the value of soil penetration resistance at different soil depths (0 - 60 cm). This research aimed to determine soil penetration resistance at different coffee plantation ages with different soil depths and to analyze the relationship between soil penetration resistance with soil physical characteristics and coffee productivity. The survey activities include observation of minipits, measuring soil penetration resistance at soil depths of 0-20 cm, 20-40 cm, and 40-60 cm using a hand penetrometer, and soil sampling. The results showed that the soil penetration resistance at each LU and soil depth suggested variation were categorized into moderate and high soil penetration resistance classes (1.34 MPa - 3.35 MPa). Soil characteristics, such as soil aggregate stability, water content, bulk density, porosity, silt content, and clay content, significantly correlate with soil penetration resistance. However, soil penetration resistance has a negative correlation with coffee productivity. The value of soil penetration resistance (at a depth of 0-60 cm) has a significant negative correlation with the average productivity of coffee plantations (r=-0.5936**). Therefore, increased soil penetration resistance decreased root growth, decreasing plant productivity.

Lemon trees require the nutrients they extract from the soil. This research aims to analyze the impact of organic matter application on enhancing soil nutrient availability and improving soil chemical properties using a pot-scale incubation experiment. This study used a completely randomized design with eight treatments and four replications. The pot treatment used 10 kg of air-dry soil per pot mixed with an organic matter dosage of 30 tons ha-1 and was observed at 2, 4, 8 weeks after applications. The treatment consisted of P1 (topsoil, control), P2 (subsoil, control), P3 (topsoil + compost), P4 (subsoil + compost), P5 (topsoil + cow manure), P6 (subsoil + cow manure), P7 (topsoil + goat manure), and P8 (subsoil + goat manure). The results indicated that compost and manure fertilizer had a significant effect in increasing soil chemical properties (pH, organic carbon content, cation exchange capacity, total-N, available-P, and exchangeable-K), with topsoil treatment having the highest value compared to the subsoil treatment, almost at all parameters. The topsoil treatment + 30 tons ha⁻¹ cow manure significantly increased the N-total by 44.44% at 8 and 12 WAA on the control treatment. The topsoil treatment + goat manure 30 tons ha-1 significantly increased P-available by 13.63 - 29.74% and exchangeable-K by 40.61 - 62.88% at 4, 8, and 12 WAA against the control treatment. Based on these findings, the best fertilizer method of topsoil treatment + 30 tons ha⁻¹ of manure is recommended to increase the soil fertility of the lemon tree soil.

Agricultural waste management remains a critical environmental concern, necessitating sustainable approaches to transform organic residues into valuable resources. Among these, composting offers an effective solution by converting biomass into nutrient-rich soil amendments and reducing the burden of waste disposal. This study aims to investigate the potential of combined agricultural waste composting for producing high-quality compost and enhancing soil properties in a coffee plantation. Eight composting treatments and three replications were formulated: P1: Saccharum officinarum leaves (100%), P2: Coffee pulp (100%), P3: Gliricidia sp. leaves (100%), P4: Saccharum officinarum leaves (50%) + Coffee pulp (25%) + Gliricidia sp. leaves (25%), P5: Coffee pulp (50%) + Saccharum officinarum leaves (25%) + Gliricidia sp. leaves (25%), P6: Gliricidia sp. leaves (50%) + Coffee pulp (25%) + Saccharum officinarum leaves (25%), P7: Coffee pulp (50%) + Saccharum officinarum leaves (50%), and P8: Coffee pulp (50%) + Gliricidia sp. leaves (50%). The findings indicated that the compost mixtures containing Gliricidia sp. leaves and coffee pulp yielded a C:N ratio of less than 25, signifying that the compost was mature. The application of compost resulted in an overall increase in soil pH, organic carbon, and total nitrogen, while also ameliorating soil structure through reduced bulk density and enhanced porosity, particularly at a depth of 30–60 cm. These results provide valuable insights for farmers and agricultural policymakers in developing sustainable waste management strategies that effectively address agricultural waste disposal challenges while improving soil fertility and promoting more environmentally friendly coffee production systems.

The lack of effectiveness of fertilization and the continuous use of inorganic fertilizers result in soil quality degradation. This research was conducted to analyses the effect of compost and manure on soil base saturation. This study used a simple Completely Randomized Design with 8 (eight) treatments and 4 (four) replications. The treatment consisted of P1 (topsoil); P2 (Subsoil); P3 (topsoil + compost); P4 (subsoil + compost); P5 (topsoil + cow manure); P6 (subsoil + cow manure); P7 (topsoil + goat manure); P8 (subsoil + goat manure). The results showed that the application of topsoil + compost significantly increased the exchangeable Ca content of the soil at 8 and 12 WAA (weeks after application). Application of goat manure on topsoil influenced increasing soil exchangeable Mg and exchangeable Na. The application of various organic materials has the effect of increasing the value of soil pH, CEC, and organic C content. The deep-placement fertilization technique is deemed effective in enhancing soil quality through chemical means, particularly by augmenting base cations and the soil's cation exchange capacity. This technology is pivotal in delivering nutrients directly to plant roots, thereby mitigating fertilizer losses caused by surface runoff and volatilization.
