In winter , low temperatures , mellow humidity and a deficiency of brightness can lead to the appearance of pathogenic fungi or to problem cause by the abasement of the plant life ' root system , mainly due to short irrigation . Although the meteorological precondition that affect the crop are not the same in summer as in wintertime , neither are the water and nutritional need of the industrial plant . " For this rationality , to prepare for the winter months , it is necessary to define specific irrigation strategies . There needs to be a more generative and differentiated balance between cheery and murky day , " allege Juan Manuel García , Projar Product Manager .
The Valencian horticultural technology company has carried out a study on the management of irrigation in winter in a hydroponic tomato farm locate in Murcia . For the mental test , measuring equipment with probes was installed on the substratum to supervise the humidity part and the electric conduction . A weather condition place to evaluate radiation therapy , humidness and temperature was also put up in the greenhouse .
In aquacultural growing systems , it is necessary for the manufacturer to understand the main characteristics of the substrate and its potential drop in social club to be able to carry out adequate irrigation management of the root zone . " In this specific crop , and base on the results find , it was reason out that a mellow content of cocoa palm fibre chips provides greater porosity to the substrate and allows greater drainage capacity , thus facilitating irrigation direction during the wintertime months . The object lens with any craw is to avoid water stress or oxygenation deficit due to deficiency or excess of urine , so it is authoritative to endeavor for stable humidness and electrical conduction in the root zone of the works . In this way , the peak productive potency will be maintained ahead of the winter month , ” he says .
Projar is preparing a proficient guide for the producers to countenance them to define an adequate irrigation scheme in hydroponic crops based on the climatical status , the characteristics of the substrate and the design of the irrigation installation . “ At Projar , we want to give the producer tool by supply them all the information collected through the purpose of technology and our experience in the sphere . We realise that , now more than ever , it is important for our clients to expand and improve their agronomic knowledge for be competitive and lead the market . We go for that this information will be interesting and utile for the producer , ” say Juan Manuel .
