“…The purpose of cutting soil is to change soil structure and composition for jet fertilization. With the growth of fertilizer prices, the existing fertilizer application techniques have shown a trend away from the conventional spreading technique towards injection, which means that fertilizers are directly injected into the soil and deposited near the plant roots [85,86]. Compared with injection methods such as spokes, furrow openers, jet fertilization as an application of liquid jet technology can effectively avoid crop damage, fertilization holes blockage, and soil contact parts wear and tear [87].…”

Cutting is a significant part of agricultural material processing, and the cutting technology determines the quality of agricultural products. Water jet cutting technology is a non-contact and cold cutting technology suitable for cutting agricultural materials. It can realize an environmentally friendly cutting process avoiding such problems as heat generation, sharpening and cleaning blades, and microbial cross-contamination. This paper reviews the current status of water jet cutting of six kinds of agricultural materials, including vegetables, fruits, meats, woods, stems, and soils. By analyzing how to complete different cutting operations, improve cutting ability, or control post-cutting influences, the problems and solutions of water jet cutting of each material are summarized. Then, combined with the application requirements, some suggestions are put forward for developing water jet cutting technology. The results would help researchers determine key information required by cutting agricultural materials and provide a reference for further research on water jet cutting technology in agricultural engineering.

“…In the nurseries, a fertilizer dosing device is used, which arranges the NPK ratio correctly during the fertilization process of seedlings. The importance of NPK dosing was also mentioned in [26] and it comes from the prevention of nutrient losses. Authorized staff in the establishments also indicated that the use of excess or less fertilizer due to the dosing device directly affects the healthy development of the plant.…”

Seedling grafting is an essential technique that is often expressed as the fusion of two different small plants to make an organism with superior properties. Grafted seedlings have strategic and economic importance because they affect the yield of other agricultural products and final product quality. However, grafted seedling production consumes more resources than normal seedlings; therefore, its environmental effects carry great importance for sustainable agricultural production whilst in life-cycle assessment (LCA) literature, little research exists about this subject. This cradle-to-farm-gate LCA study focuses on grafted tomato seedling production in Antalya, Turkey and original data compiled by face-to-face surveys with seedling producers are used. It aims to analyze and discuss the environmental impacts of energy, fertilizers, pesticides, disinfectants, peat, perlite, vermiculite, inserts, trays, grafting sticks, clips, plastic sheeting, packaging used in production. Findings reveal that coal for greenhouse heating in the energy category and expanded polystyrene (EPS) trays in supporting materials category have higher impacts. Therefore, rigid plastic alternatives of EPS with higher recycling potential are discussed. After creating a scenario to compare EPS and high-density polyethylene (HDPE) as raw materials, the results indicate that HDPE has lower damage potential than EPS in the human health, ecosystems, and resources categories.

“…Liquid fertilizer deep-fertilization technology is an agricultural technology which applies fertilizer at the root of crops by means of deep-fertilization mechanism. This method can directly deliver the nutrient composition of liquid fertilizer to the root system of crops, promote their absorption of nutrients, improve the utilization and reduce the run-off of fertilizer, which can lower the cost of agricultural production and protect the environment (da Silva et al, 2017;Jagvir et al, 2018;Zhou et al, 2016). Deep-fertilization mechanism is a key part of liquid fertilizer deep-fertilization applicator; hence it is very necessary to develop a liquid fertilizer deep-fertilization applicator suitable for Chinese situations.…”

“…Therefore, this paper proposed a liquid fertilizer injection deep-fertilization mechanism with deformed gears. As deformed gears can realize the vertical and horizontal changes of transmission ratio (Da Silva et al, 2017;Jin et al, 2018;Thomas, 2002), this type of deep-fertilization mechanism can improve the perpendicularity to the soil and further reduce the fertilizer loss. Then, bench test was performed on the deep-fertilization mechanism with deformed gears.…”

Deep-fertilization mechanism is a key part of deep-fertilization liquid fertilizer applicator. To obtain a good-performance deep-fertilization mechanism, this study developed a deep-fertilization mechanism with deformed gears and designed a deformed gear fertilization test bench. Single-factor and central composite design tests were performed with the planet carrier, spray hole size and pump pressure as the test factors, and the fertilizer amount as the test index. The results of the single-factor test showed a linear functional relationship between fertilizer amount and pump pressure, an exponential functional relationship between planet carrier velocity and fertilizer amount, and an exponential relationship between spray hole size and fertilizer amount. The rotating and perpendicular test data were analyzed and optimized using Design-Expert 8.0.5 software. The result of the optimization is: 10.5ml of fertilizer amount with pump pressure 0.36MPa, planet carrier velocity 82 r/min, and spray hole size 2 mm. The test result can meet the agronomic requirements.
