Agricultural production systems currently face multiple challenges: Climate change, natural resource depletion, and supply chain disruption, together with global population growth. As sustainable agriculture must simultaneously deliver myriad services (e.g. provide food security, maintain natural resources, retain and improve framers' profitability, and sustain biodiversity), a systemic and multidisciplinary approach is thus needed. In this context, new technologies based on sensors, automatic machines, robots, and digital applications show much potential. The special section of the Agronomy Journal, entitled, "Agricultural and Biological Sciences: Plant, Soil, Animal and Environment Nutrient Management," brings together a coherent set of research studies. All papers published in this special section address current, relevant topics for agriculture, biology and environmental sciences with a multidisciplinary approach aimed at generating new scientific information on digital technologies, bioinformatics, plant science, soil resources, agricultural waste, and environmentally conscious approaches. A total of 58 papers were submitted, each of which was evaluated by expert reviewers using a double-blind reviewing process and 25 full text papers were accepted for publication in the special section. The present paper highlights the findings of the published papers, with the aim of bringing cuttingedge innovation to applied research in agriculture and biology. The published papers here provide new knowledge and viable solutions for better performance in agricultural and biological sciences. New technologies will change the concept of farming and agribusiness making it more profitable, efficient, safer, attractive, simple, smart, and finally sustainable. Rural development and food security policies must support and finance the easiest possible access to new technologies for agricultural producers.

“…Currently, the forms of fertilizer used in tea gardens are becoming increasingly diverse, including organic manures [20,21], rapeseed cake [6], and chemical fertilizers [22]. However, all these fertilizers are applied through ditching manually [23]. Compared to traditional fertilization methods, drip fertilization systems have been repeatedly proven to be beneficial for forming a good root structure, improving crop yield and quality, and reducing environmental risks [24].…”

Applying nitrogen fertilization is an important way to improve the yield and quality of autumn tea (Camellia sinensis L.), but the effects of nitrogen application rate and nitrogen form still remain unclear. Field experiments were conducted in a drip-irrigated tea garden in Rizhao City, China in 2020 and 2021. The effects of nitrogen application levels (N: 0 kg·hm−2, CK; N: 45 kg·hm−2, U1; 75 kg·hm−2, U2; and 105 kg·hm−2, U3) and nitrogen application forms (ammonium bicarbonate, AB; ammonium bicarbonate + urea, UAB; and urea, U) on soil moisture, as well as nitrogen spatiotemporal change, and autumn tea yield and quality, were studied. Results showed that applying ammonium bicarbonate or urea through a drip irrigation system can significantly increase the tea plant evapotranspiration and the autumn tea yield and quality (including free amino acids and tea polyphenols). With the same nitrogen application, the urea fertilization treatment had the higher ammonium nitrogen content within the 0–60 cm soil layer. The application form of nitrogen fertilizer had a significant impact on the yield of autumn tea, and the yield increasing ability was U > UAB > AB. The partial factor productivity of applied nitrogen under the AB treatment was the lowest. The yield-increasing effect of nitrogen fertilizer can be observed only 16–18 days after topdressing through the drip irrigation system. In 2020 and 2021, the yield of autumn tea under the U3 treatment increased by 40.6% and 23.0%, respectively, compared with the CK treatment. In conclusion, the topdressing with urea 105 kg·hm−2 with drip irrigation for tea plants in autumn is recommended. This recommendation will provide a theoretical basis for efficient irrigation and yield increase in tea gardens.
