Dry summers and cold, wet winters make perfect conditions
Because almonds dry in the orchard, dry summers offer ideal growing conditions. With a limited canopy and relatively shallow but wide root systems, almonds are extremely water-sensitive. If the nuts receive rain week after week, the trees are prone to rot. Therefore, effective application and management are critical.
The trees need about 10 000 cubic metres of water per hectare per season. The irrigation system mainly relies on rainwater and water from the mountain. They also use the Suid-Agter Paarl irrigation scheme to supplement their storage dams.
The irrigation that Magnus and his team are familiar with in the vineyards is less intensive than that for almonds, he believes. Therefore, they approached the Agrico team. They knew exactly what the requirements were according to their specific needs.
Magnus tells about their irrigation journey: “We have been doing business with Agrico for years, and I have come a long way with their designer, Gerrie van Zyl. The advantage of Agrico’s experts is that they are familiar with the area, which helped us a lot in setting up the system.”
“Here at Vrymansfontein, we have fairly heavy clay soil, so we established double-line drippers with 600 mm spacing (since heavy soil saturates fairly quickly) that deliver 1,6 litres per hour.
The efficiency of the drippers was the key factor at Vrymansfontein. With limited additional water supply, they need to manage water sparingly – something a drip system is designed to do.
“Drip irrigation gives us the best water usage with minimal water waste. We work at 9 000 to 11 000 cubic metres per hectare per block for optimal almond production in our area. Another advantage is the ability to place water precisely where it is needed. Our tree nutrients also go through our fertiliser system, which is applied by the drippers directly at the roots, where it is crucial.”
Smart water management using the latest technology
Magnus explains that they use the irrigation programme Irrigator to apply water automatically and on schedule. They also use Phytech, which, with the help of a weather station, assesses the trees’ water needs and monitors soil moisture, enabling informed decisions on water application.
The almonds at Vrymansfontein are watered twice a day in peak season. At 10:00 in the morning, three-fifths of the day’s water needs are supplied, and in the afternoon, the rest is given.
Experts in the field with Agrico by their side
Magnus tells that it is great to work with experts in the field. “Because our systems are quite new, we had a lot to learn. Agrico designed the system very well from the beginning, based on expert advice that helped us set up the right pump systems and irrigation systems here.
“During the installation of the system, there was always someone from Agrico with the necessary knowledge present on-site. Even though we could not be on the farm every day ourselves, it gave us so much peace of mind to know that we were in good hands.
“With Agrico, we also know that we shall get the best products at the best prices. Everything works perfectly and is at the forefront of technology applicable to us. We truly have a good understanding with Agrico, and we look forward to what the future holds!”
