What is the best way to monitor my irrigation and fertilization?
There are two useful ways to monitor irrigation and fertilization.
Drainage: Drainage helps to make sure that you irrigate the right volume and that you don’t accumulate salt in your substrate, which could harm your plants. Carrying out chemical analysis of both drainage water and irrigation water at least once every two weeks will help to expose an unbalanced process.
Soil moisture sensors: These will help you to continually monitor water content in your substrate. Once you're familiar with your crop and substrate, you can adjust irrigation and fertilization schedules for optimum yield.
What are the benefits of Compensated Non-Leakage (CNL) drippers?
Irrigation of soilless media is done through short irrigation pulses. CNL drippers help you increase fertigation uniformity by preventing system drainage and thus eliminating the refilling time of the system. That means all the drippers start and stop at the same time every irrigation cycle, guaranteeing equal quantities of water and fertilizers to all plants.
How do the EC and pH affect my greenhouse tomatoes?
Getting the right EC, pH and nutrient levels in your root zone makes for much faster-growing and high yielding crops. This is especially true when growing in soilless media, since the growing medium has low buffer capabilities and demands a fast, precise reaction.
A precision drip system can often help in delivering the right nutrient level to your plants. It allows you to keep all parameters exactly where you need them and to react to changes on demand.
What is pulse irrigation and why is it so common in substrate cultivation?
Pulse irrigation is an approach that uses frequent irrigations with short durations. The objective is to match the application rate of the irrigation system with the absorption rates of the substrate, so no water or nutrients are wasted. This is done by applying the water in cycles of short duration irrigation, followed by a rest period. That rest lets the substrate absorb the water before more is added.
