Presently, there is a growing interest in developing new controlled-release fertilizers based on ecological raw materials. The present study aims to compare the efficacy of two new ureic-based controlled-release fertilizers formulated with water-soluble polymeric coatings enriched with humic acids or seaweed extracts. To this end, an experimental approach was designed under controlled greenhouse conditions by carrying out its subsequent field scaling. Different physiological parameters and crop yield were measured by comparing the new fertilizers with another non polymeric-coated fertilizer, ammonium nitrate, and an untreated ‘Control’. As a result, on the microscale the fertilizer enriched with humic acids favored a better global response in the photosynthetic parameters and nutritional status of wheat plants. A significant 1.2-fold increase in grain weight yield and grain number was obtained with the humic acid polymeric fertilizer versus that enriched with seaweed extracts; and also, in average, higher in respect to the uncoated one. At the field level, similar results were confirmed by lowering N doses by 20% when applying the humic acid polymeric-coated produce compared to ammonium nitrate. Our results showed that the new humic acid polymeric fertilizer facilitated crop management and reduced the environmental impact generated by N losses, which are usually produced by traditional fertilizers.

新型生态友好型聚合物包膜尿素肥料可提高小麦的作物产量
当前,对基于生态原料开发新型控释肥料的兴趣与日俱增。本研究旨在比较两种新的以尿素为基础的控释肥料的功效,这些肥料是由富含腐殖酸或海藻提取物的水溶性聚合物涂层制成的。为此,通过控制温室的后续规模,设计了一种在受控温室条件下的实验方法。通过将新肥料与另一种非聚合物涂层肥料,硝酸铵和未经处理的“对照”进行比较,测量了不同的生理参数和农作物产量。结果,在微观尺度上,富含腐殖酸的肥料有利于小麦植物的光合参数和营养状况更好的全球响应。重大1。与富含海藻提取物的腐殖酸聚合物肥料相比,腐殖酸聚合物肥料的谷粒重量产量和谷粒数量增加了2倍。并且平均而言,相对于未涂覆的涂层更高。在田间,与硝酸铵相比,施用腐殖酸聚合物涂层产品时,将氮剂量降低20%,可以证实类似的结果。我们的结果表明,新型腐殖酸聚合肥料可促进作物管理并减少氮肥损失对环境的影响,而氮肥损失通常是传统肥料造成的。与硝酸铵相比,施用腐殖酸聚合物涂层产品时将氮剂量降低20%,可以证实类似的结果。我们的结果表明,新型腐殖酸聚合肥料可促进作物管理并减少氮肥损失对环境的影响,而氮肥损失通常是传统肥料造成的。与硝酸铵相比,施用腐殖酸聚合物涂层产品时将氮剂量降低20%,可以证实类似的结果。我们的结果表明,新型腐殖酸聚合肥料可促进作物管理并减少氮肥损失对环境的影响,而氮肥损失通常是传统肥料造成的。
