An evaluation of the Olsen test as a measure of plant-available phosphorus in grassland soils derived from basalt parent material

Abstract. Anecdotal and circumstantial evidence have suggested that the Olsen test underestimates plant-available phosphorus (P) in basaltic soils in Northern Ireland. Therefore, the ability of this test to predict plant-available P in basaltic (and non-basaltic) soils was investigated by regressing Olsen-P data against herbage P indices calculated from plant tissue test data using the diagnosis and recommendation integrated system. The average Olsen-P concentration for a range of fields situated on basaltic soils was considerably lower than the average Olsen-P concentration for a range of fields situated on non-basaltic soils, and yet mean sward P status, as given by the herbage P indices, was similar for both groups of fields. Herbage P indices were also much better correlated with Olsen-P measurements in non-basaltic soils than in basaltic soils. Furthermore, at low Olsen-P values (≶9mgPL⁻¹) some swards on basaltic soils were genuinely deficient in P, while others were sufficient or even in surplus for this nutrient. The results confirm that Olsen-P is inadequate as a predictor of plant-available P in basaltic soils. It is concluded that an alternative soil test is needed to provide a reliable assessment of plant-available P in basaltic soils, to prevent overuse of fertilizer and manure P and to minimize the amounts of P entering local watercourses.

运用模糊数学和灰色系统理论分析评价夏播花生区试品种

运用模糊数学和灰色系统理论，对2007年河南省夏播花生区试品种进行了多因素综合评价和分析，结果表明：周花4号评价指标是0．7089，综合表现最优；其次是W9847—1—3—4—1，其综合评价指标是0．6352；豫花6号评价指标是0．3630，综合表现最差。此结果与试验地实际表现基本相一致。     

完善农村居民最低生活保障制度的几点建议

当前，我国农村普遍建立了居民最低生活保障制度，这是保障农村社会稳定的“最后一道安全网”，是中国农村社会保障体系的基础工程。但是，我国农村居民最低生活保障制度也还存在一些问题，例如保障对象、保障方式、保障资金、管理体制等，充分认识并采取 有效措施解决好这些问题，对于完善农村社会保障体系，维护农村社会稳定和经济发展有着重要现实意义。     

我国中央山系东段演化及其对黄河河道及东平湖的影响

根据2603a有史记载以来黄河河道变迁和春秋以来东平湖演变历史，本文提出我国中央山系东段碰撞和松弛导致的地势上升和下降是影响黄河河道变迁和东平湖演变的重要因素。山系碰撞上升造成黄河河道向北西迁移，东平湖湿地北漫；山系松弛下降导致黄河河道向东南迁移，东平湖南泛。
