“…The grass type and coverage have obvious effect on soil salinity and alkalinity of the soda saline soil in Songnen Plain in China. Soil improvers (straw, gypsum, and animal manure) obviously affect the biochemical characteristics of salinized soil in the YRD (R. T. Wang et al, 2017; H. Zhang et al, 2016).…”

The effects of different straw returning and nitrogen addition levels on soil quality are important for proper coastal saline soil remediation. However, relatively little is understood concerning the remediation effects, especially, on long‐term effects and mineral composition and microstructures of coastal saline soil. Two maize/wheat straw returning levels [1.0 × 104 kg ha−1 (2S) and 5.0 × 103 kg ha−1 (S)] and three inorganic nitrogen addition levels [300 kg ha−1 (N2), 150 kg ha−1 (N) and 75 kg ha−1 (N1/2)]—were studied, with 150 kg ha−1 inorganic nitrogen and without straw addition treatment as the control (CK), to elucidate the response of soil physical and chemical properties to the two factors. After four consecutive wheat‐maize cycles, different straw and N fertilizer treatments obviously decreased the salinity contents, increased the total nutrient contents, and optimized the soil structure of the saline soil. The saline soil reclamation effects showed significant distinctions among the different straw and N fertilizer treatments. The 2SN2 treatment displayed the greatest effects in regard to reducing salinity, increasing the total soil nutrient contents and optimizing the soil structure, which resulted in the best remediation effect. Straw returning plays a major role in decreasing soil salinity and enhancing saline soil aggregate formation. N fertilizer addition supplies rich nutrients for straw decomposition, and promotes soil microbial growth and reproduction, which brought about C sequestration in coastal saline soil. During the coastal saline soil remediation process in the Yellow River Delta, it is suggested to prioritize straw returning and moderate N fertilizer addition, and live together with moderate P fertilizer application.

“…Повышение солености почвы приводило к большей токсичности при влиянии Pb [9]. Биохимические показатели почв, в том числе ФА по каталазе и уреазе, успешно применены для оценки качества влияния четырех видов мелиорантов на засоленные почвы дельты р. Желтая с целью использования этих почв в сельском хозяйстве [10]. Уреазная активность почв использовалась с целью оценки скорости минерализации органического азота в соленых почвах дельты этой реки при использовании в качестве мелиоранта биоугля [11].…”
