Soil salinization is a significantconstraint affecting the productivity of agricultural land worldwide. This led to abandoning production farmcrops on colossalland. salinity inversely affects seed germination and plant growth influences plant’s biological activities like photosynthesis, respiration, metabolism, enzymatic activities, hormone regulation, etc. Therefore, efforts are being made bring saline soil under cultivation by improving itthrough proper drainage system drain out salts orapplying chemical amendments. However, these options costly energy-intensive for employment in large areas vast scale. In this direction, biologically cost-effective approaches also practiced improve degraded lands. Phytoremediation, plant-based approach soil, may be an appropriate option. done plantation salt-tolerant species, which can remove leach down excess sodium (Na<sup>+</sup>) from enhance calcium (Ca<sup>2+</sup>) through cation exchange process root zone. During process, remarkable properties soil-aggregates stability, proliferation, hydraulic properties, nutrient availability plants improved. Such improvement facilitates less tolerant improves environment general climatic conditions enhancing carbon sequestration.

Abstract Grazing annual forages in dryland cropping systems has been used to integrate crop and livestock systems, rejuvenate soils, enhance in‐field nutrient cycling soil organic carbon (SOC), increase net returns by eliminating harvest expenses feed delivery. However, cattle ( Bos taurus ) could potentially degrade physical properties increasing compaction reducing water infiltration no‐tillage (NT) systems. Minimum tillage (MT) may help correct some of these potential quality concerns. The objective this study was quantify MT effects on properties, forage mass, weeds compared NT a grazed winter triticale [× Triticosecale Wittm . ex A.

Abstract Protein, derived from plant and microbial residues, constitutes a significant portion of soil nitrogen or organic carbon pool plays crucial role in determining sequestration. Though diversifying species has been regarded as promising strategy for promoting accumulation during vegetation restoration afforestation, how increasing diversity (PSD) would influence protein remains unknown. We selected 45 plots covering natural gradient PSD, which was reflected by the Shannon index varied 0.15 to 3.57, subtropical karst forest. The major objective investigate impact PSD on abundance, with depolymerization rate multiple biotic abiotic variables being measured explore underlying mechanism. relative abundance protein, that is proportion matter between 24.1 34.0% an average 29.2 ± 2.3% across plots.
