Special Issue Information

Dear Colleagues，

The adaptation of horticulture to global changes, soil degradation and water scarcity involves new technical and management solutions, particularly in dryer areas. This issue is emergent due to the adverse impacts of global and climatic changes threatening to reduce the water available for agriculture and the increased demands of society for horticultural products and services, such as food, medicinal, environmental, and social ones. The digitization of agriculture offers new solutions to deal with many of the new problems, through information technologies that enhance the collection of data by sensor systems, the automation of many processes allowing to optimize the effectiveness of operations and the efficiency of the use of resources, eventuating in greater sustainability and resilience of agricultural production. New developments are appearing, such as: the water management of irrigation systems, including hydroponic with the inherent irrigation scheduling, and fertigation; monitoring of soil moisture, salinity, nutrients, plants and weather, and communication technologies systems to support the crop and soil management.

This Special Issue will focus on recent developments of horticultural technology and practice, particularly related with water and soil management. These developments will contribute to clarify some current questions and point out feasible solutions for specific real problems, particularly on water scarcity and soil conservation contexts.

Submissions on the following topics are encouraged: (1) Irrigation management, including scheduling optimization, and systems operation control and automation aiming water and energy savings. (2) Crop management and fertilization, including crop local and remote sensing, controlled deficit irrigation and yield optimization. (3) Soil management techniques like organic and mineral fertilization, tillage intensity, application of manure, biochar and char, mulching, seaweeds, and plant residue management. (4) Management strategies controlling nutrient input and losses applying digital and precision techniques and modelling.

Estimation of Evaporation and Drought Stress of Pistachio Plant Using UAV Multispectral Images and a Surface Energy Balance Approach
by Hadi Zare Khormizi, Hamid Reza Ghafarian Malamiri and Carla Sofia Santos Ferreira

Water scarcity is a critical abiotic stress factor for plants in arid and semi-arid regions, impacting crop development and production yield and quality. Monitoring water stress at finer scales (e.g., farm and plant), requires multispectral imagery with thermal capabilities at centimeter resolution. This study investigates drought stress in pistachio trees in a farm located in Yazd province, Iran, by using Unmanned Aerial Vehicle (UAV) images to quantify evapotranspiration and assess drought stress in individual trees. Images were captured on 10 July 2022, using a Matrix 300 UAV with a MicaSense Altum multispectral sensor. By employing the Surface Energy Balance Algorithm for Land (SEBAL), actual field evapotranspiration was accurately calculated (10 cm spatial resolution). Maps of the optimum crop coefficient (Kc) were developed from the Normalized Difference Vegetation Index (NDVI) based on standard evapotranspiration using the Food and Agriculture Organization (FAO) 56 methodology. The comparison between actual and standard evapotranspiration allowed us to identify drought-stressed trees. Results showed an average and maximum daily evaporation of 4.3 and 8.0 mm/day, respectively, in pistachio trees. The real crop coefficient (Kc) for pistachio was 0.66, contrasting with the FAO 56 standard of 1.17 due to the stress factor (Ks). A significant correlation was found between Kc and NDVI (R2 = 0.67, p < 0.01). The regression model produced a crop coefficient map, valuable to support precise irrigation management and drought prevention, considering the heterogeneity at the farm scale. Full article

Seaweed polysaccharides can act as substitutes for synthetic compounds present in commercial stimulants and fertilizers used in agriculture to improve crop yields and vigor. In this study, three different polysaccharides (alginate, agar, and carrageenan) were extracted from one brown seaweed, Saccorhiza polyschides, and two red seaweeds, Gracilaria gracilis and Chondrus crispus, respectively, and applied to potted turnip greens (Brassica napus L.), with the intention to analyze their impact on plant growth, development, and metabolism. Turnip greens treated with polysaccharides, especially carrageenan of C. crispus, showed the best results in improving the crop productivity in terms of plant length and weight, number of leaves, nutrient and pigment content, and soil fertility compared with turnip greens from the negative control or those treated with a commercial leaf fertilizer. λ-carrageenan extracted from the tetrasporophyte generation of C. crispus had the highest bioactivity and positive effect on turnip greens among all treatments. λ-carrageenan has been shown to improve plant growth; increase the plant’s biomass (plant leaves: CC(T) (40.80 ± 5.11 g) compared to the positive control (15.91 ± 15.15 g)) and root system; enhance photosynthetic activity; increase the uptake of soil nutrients; and protect plants against abiotic and biotic stresses, stimulating the production of secondary metabolites and managing its defense pathways. Seaweed-extracted polysaccharides have the potential to be used in sustainable agriculture. Full article
