Impact of the Belding's ground squirrel, Spermophilus beldingi, on alfalfa production in northeastern California [PDF]
, 1984 The Belding ground squirrel (Spermophilus beldingi) is found in rangeland, pasture, and various agronomic crops. However, its impact on agricultural production has been measured only rarely, e.g., by Grinnell and Dixon (1918) and Sauer (1976, 1977).

Netherlands Journal of Agricultural Science, 1962 The economics of sprinkler irrigation and of surface irrigation are theoretically analysed for areas where water is in short supply. It is postulated that where crop yields and general expenses per unit area are equal for the 2 systems, sprinkler irrigation will be the more profitable because a greater area of land can be irrigated with the same ...

Lawn irrigation with domestic wastewater by subsurface drip or sprinkling [PDF]
Ornamental Horticulture, 2020 Abstract To maintain the quality of a lawn and allow it to perform its functions (esthetics, enhancement of property, reduction of air temperature, etc.) efficient use of irrigation and adequate fertilization are necessary. The use of wastewater from sewage treatment, which has a nutrient load, in irrigation, can be an alternative especially if applied

Radicchio cultivation under different sprinkler irrigation systems [PDF]
, 2016 Gun sprinklers were commonly used in Italy to irrigate Radicchio. Although this high-pressure irrigation system allows large areas to be irrigated in a short time, it has some major disadvantages. Disadvantages include the impact of the drops on the soil

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity
Advanced Science, EarlyView.Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Advanced Science, EarlyView.We developed an implantable dual‐drug depot using GelMA for bone metastasis treatment, co‐delivering MSA‐2 and αB7‐H3‐loaded CaCO3 microparticles. Sustained release from GelMA scaffold enables MSA‐2 to activate STING signaling and enhance T‐cell infiltration and activation, while sequentially released αB7‐H3 blocks MSA‐2‐induced B7‐H3 upregulation ...

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean
Advanced Science, EarlyView.This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...
