Smart fertigation is a topic of great interest in the effort to optimize different activities involved in local and extensive agriculture for assisting crops, optimizing production by using wireless technologies, data-processing electronic boards and sensors network. With the advent of Agriculture 4.0, similar to Industry 4.0, Information Communication Technology (ICT), associated with mechatronics, is giving an added value to this technique allowing optimization of water, fertilizers, control of water flow in pipes and period of irrigation. This paper intends to illustrate findings related to an innovative low cost system for assisting crops and achieving an accurate farming by investigating on the design, construction, testing and control of dosing system for liquid and granular fertilizers. Four different dosage systems have been designed, realized and tested with different granular and liquid fertilizers; the analysis of an extensive experimental campaign allows to define the characteristic and the mathematical expressions for each analyzed fertilizer and for each dosage system. The accurate modeling allows to control with extreme precision the realized dosing systems after estimating the quantity of fertilizer which the crop needs by means of the smart fertigation system. The obtained results permit the optimization of the fertilizer dosage in terms of quantity, which at the same time translates into lower production costs, greater environmental sustainability and optimization of production in terms of quantity and quality.

创新的智能施肥管道中优化肥料剂量的系统:建模,构建,测试和控制

在优化与当地和广泛农业有关的各种活动以辅助农作物,使用无线技术,数据处理电子板和传感器网络来优化生产方面,智能施肥引起了极大的兴趣。随着农业4.0(类似于工业4.0)的出现,与机电一体化相关的信息通信技术(ICT)为该技术提供了附加值,从而可以优化水,肥料,控制管道中的水流和灌溉时间。本文旨在通过研究液体和颗粒肥料配量系统的设计,构造,测试和控制,来说明与创新的低成本系统有关的结果,该低成本系统可协助农作物并实现精确的耕种。设计了四种不同的剂量系统,用不同的粒状和液体肥料实现和测试;通过广泛的实验活动的分析,可以定义每种分析肥料和每种剂量系统的特性和数学表达式。精确的建模可以在通过智能施肥系统估算出农作物所需的肥料量之后,以极高的精度控制已实现的配量系统。所获得的结果使得可以在数量上优化肥料用量,同时转化为更低的生产成本,更大的环境可持续性以及就数量和质量而言的生产优化。通过广泛的实验活动的分析,可以定义每种分析肥料和每种剂量系统的特性和数学表达式。精确的建模可以在通过智能施肥系统估算出农作物所需的肥料量后,以极高的精度控制已实现的配量系统。所获得的结果使得可以在数量上优化肥料用量,同时转化为更低的生产成本,更大的环境可持续性以及就数量和质量而言的生产优化。通过广泛的实验活动的分析,可以定义每种分析肥料和每种剂量系统的特性和数学表达式。精确的建模可以在通过智能施肥系统估算出农作物所需的肥料量后,以极高的精度控制已实现的配量系统。所获得的结果使得可以在数量上优化肥料用量,同时转化为更低的生产成本,更大的环境可持续性以及就数量和质量而言的生产优化。精确的建模可以在通过智能施肥系统估算出农作物所需的肥料量之后,以极高的精度控制已实现的配量系统。所获得的结果使得可以在数量上优化肥料用量,同时转化为更低的生产成本,更大的环境可持续性以及就数量和质量而言的生产优化。精确的建模可以在通过智能施肥系统估算出农作物所需的肥料量之后,以极高的精度控制已实现的配量系统。所获得的结果使得可以在数量上优化肥料用量,同时转化为更低的生产成本,更大的环境可持续性以及就数量和质量而言的生产优化。
