“…First, at each subplot, shoots were harvested by shear and then divided into leaves and stems, in which flowers were classified as stems. Second, the root auger with a 10-cm inner diameter was used to collect a soil column with a 20-cm layer at this subplot, and this soil column was screened out of garbage and stones and then divided into root samples and soil samples using a 2-mm sieve (Duan et al, 2024). The leaves, stems, and roots were placed into envelopes, and the soil samples were collected in fabric sample bags and carried back to the laboratory.…”

Plant and soil C:N:P stoichiometry reflects the element content and energy flow, which are important for biogeochemical cycling in ecosystems. Although plantation age has been verified to affect leaf C:N:P stoichiometry in alfalfa plants, its effect on plant and soil C:N:P stoichiometry in grass remains poorly documented. A 10-year field experiment of Kentucky bluegrass (Poa pratensis) was used to test how plantation age affect plant and soil C:N:P stoichiometry in a perennial rhizomatous grass pasture. This study demonstrated that leaf C:N, C:P, and N:P ratios exhibited a rapid increasing trend from 2 to 6 years of age, whereas leaf C:N showed a slight decreasing trend, and leaf C:P and N:P maintained stability from 6 to 9 years of age. Stem C:N and N:P were not different among plantation ages, while stem C:P increased from 2 to 4 years of plantation age and then maintained stability from 4 to 9 years of plantation age. Root N:P showed an increasing trend from 2 to 6 years of plantation age and relative stability from 6 to 9 years of plantation age, whereas root C:N and C:P showed decreasing trends from 2 to 9 years of plantation age. Although soil C:P did not differ among nine plantation ages, soil C:N and N:P remained relatively stable from 2 to 6 years of plantation age. However, soil C:N showed a decreasing trend, while soil N:P showed an increasing trend after 6 years of plantation age. The results from an ecological stoichiometric homeostasis analysis further showed that N in the leaf, stem, and root and P in the stem had strict homeostasis, whereas P in the leaf and root showed plastic and weakly homeostatic status, respectively. These results present a pattern concerning the plantation age in relation to plant and soil C:N:P stoichiometry in a perennial grass and provide useful information for N and P management in Kentucky bluegrass pastures.

In light of the current water scarcity, one strategy for reducing water consumption in irrigated agriculture is to reduce the amount of irrigation water compared to full crop irrigation or in other words deficit irrigation. Deficit irrigation management may be a critical issue due to climate change. Incorporation of different soil conditioners can improve soil hydro-physical properties and mitigate negative effects in water-stressed conditions. Recent review articles either addressed specific crop behavior under water deficit or covered a single type of soil conditioners. This manuscript represents an inclusive review providing insight into deficit irrigation methods incorporated with different soil conditioners. Crop response to deficit irrigation is discussed in the light of some mathematical models. Three main types of soil conditioners are covered: bentonite, biochar, and super-absorbent polymers. Mechanisms associated with effects of each conditioner to enhance soil water retention is highlighted as well. Previous study findings were discussed comparatively and future prospective, recommendations and challenges were addressed.
