“…In dry seasons RT shortens and water exchange level declines when Phophsphorus mass is retained.. Two environmental ecosystems have an impact on P concentration in the Agmon-Hula waters: 1) the Lake itself with submerged plants and chemo-physical processes (sedimentation, phosphorus cycling, etc.) (Gophen 2000; Gophen et al 2001; Symhayov et al 2013); and 2) peat organic soil and water (precipitation, irrigation) flushing (Yatom and Rabinovich 1999; Yatom et al 1996; Litaor et al 2013, 2014; Haygarth et al 2013; Reichman et al 2013). Plant-mediated phosphorus and geo-chemical processes in the peat soil have a major impact on the lake ecosystem, with the first dominant in summer and the second in winter.Considering that plant-mediated phosphorus has a major impact on the lake ecosystem and geo-chemical processes inside the Peat soil as dominant, the domination of the first occur in summer and that of the second in winter.…”

“…Later on, as a consequence of inundation due to water level fluctuation, P availability along the narrow beach stripe increased and Typha vegetation was renewed. The organic peat soil in the Hula Valley is a P-rich habitat (Litaor et al 2013, 2014; Reichman et al 2013; Haygarth et al 2013). Nevertheless, there is a storage of 22–37 and 11–22 tons of P in the upper two 5-cm layers, respectively, in the Agmon-Hula bottom sediments (Gophen 2000).…”

“…Phosphorus, manganese, and organic matter relations in the Hula Valley peat soil have been widely studied (Gophen et al 2014; Haygarth et al 2013; Litaor et al 2013; 2014; Reichman et al 2013; 2016; Yatom and Rabinovich 1999; Yatom et al1996;Xiang et al 1996; Barnea 2009). The impact of geochemical parameters of pH, oxidation–reduction (redox), wettability (rainfall, irrigation), soil properties, temperature, and agricultural management (fertilization) conditions on the dynamics of phosphorus and peat soil particle bound–release relations had been thoroughly investigated in those studies.…”

Part of the Kinneret watershed, the Hula Valley, was modified from wetlands –shallow lake for agricultural cultivation. Enhancement of nutrient fluxes into Lake Kinneret was predicted. Therefore, a reclamation project was implemented and eco-tourism partly replaced agriculture. Since the mid-1980s, regional climate change has been documented. Statistical evaluation of long-term records of TP (Total Phosphorus) concentrations in headwaters and potential resources in the Hula Valley was carried out to identify efficient management design targets. Significant correlation between major headwater river discharge and TP concentration was indicated, whilst the impact of external fertilizer loads and 50,000 winter migratory cranes was probably negligible. Nevertheless, confirmed severe bdamage to agricultural crops carried out by cranes led to their maximal deportation and optimization of their feeding policy. Consequently, the continuation of the present management is recommended.

Achieving Global Food Security through Sustainable Development of Agriculture and Food Systems with Regard to Nutrients, Soil, Land, and Waste Management

Ensuring that the food supply both keeps up with current population growth and changing food preferences are the main challenges of agriculture. Food security includes access to a sufficient amount of quality food products. Population growth, food preferences and economic wealth are variables that drive agricultural production, although agriculture does produce raw materials other than for food. The world population of 9 billion projected for 2050 will require food production to increase by 50 % to 70 %, with raw materials and waste increasing by the same percentages. However, there will be no significant changes in the amount of arable land; the increase in production will come about through agricultural intensification, the disparity between real and potential yield being known as the yield gap. Innovation in management techniques will focus on optimizing water use, both for irrigated and rain-fed crops. In addition, nutrient management will have to be intensified to fill the production gap. Sustainable management focuses on improving nutrient efficiency, but also includes waste management. Sustainable agriculture must introduce a circular economy model and reverse logistics for waste management, and in particular to the nutrient cycle.

Optimum Olsen Phosphorus/Zinc_DTPA ratio for the initial growth of maize in agricultural soils of the Mediterranean region

et al. 2020

BACKGROUND Zinc (Zn) deficiency in crops is commonly aggravated by high levels of phosphorus (P) in soil. In this work, the initial performance of pot‐growing maize in response to the available P and Zn in soils with low available Zn and to the application of P and Zn fertilizers was investigated. RESULTS The soils (six non‐calcareous and 14 calcareous) ranged widely in available P (Olsen P: 5.5–37.9 mg kg−1), were poor in available Zn [diethylenetriaminepentaacetic acid‐extractable Zn (ZnDTPA): 0.20–0.84 mg kg−1] and had an Olsen P/ZnDTPA ratio of 13 to 111 mg mg−1. Soil P application generally increased aerial dry matter (ADM) yield; Zn increased ADM yield mostly when applied in combination with P; and the sole application of Zn increased yield only in a soil with a high (28 mg kg−1) Olsen P and a low (0.36 mg kg−1) ZnDTPA. The increase in ADM yield resulting from optimal application of P and/or Zn to the soil was modest in soils where the Olsen P/ZnDTPA ratio was 30–60 and Olsen P was >14 mg kg−1. Zinc uptake by the control plants was correlated with the ZnDTPA of the soil. For a certain ZnDTPA value, the level of plant available Zn was higher in non‐calcareous than in calcareous soils. CONCLUSION Soil application of fertilizer P and Zn, in soils with low levels of available Zn, should not only aim at increasing the available P and Zn levels but also balancing them at the appropriate Olsen P/ZnDTPA ratio, which was found to lie in the 30–60 range in the present study. © 2020 Society of Chemical Industry
