How to protect crops against high temperatures?

One of the factors that have the greatest impact on crops and cause the greatest economic losses are temperatures and weather conditions, whether extremely cold or extremely hot, as well as other meteorological phenomena such as hail.

With the arrival of summer, the temperature rises and, due to the negative effects of climate change on the atmosphere, heat waves are increasingly more pronounced.

The effects of heat stress and high temperatures on crops are very easy to identify. Decreased photosynthesis in plants during hot days reduces plant respiration, leading to oxidation and deterioration of plant tissues. These results can be seen very clearly, and at a glance, in burns on young leaves and shoots and wilting of the plants.

At EDYPRO we have prepared these tips that may be useful to protect your crops from excess heat.

1-Increase water frequency (not irrigation time). This means increasing the number of irrigations that are carried out on your crop or farm. It is important that the water reaches the bulb, which is the area where the root of the plant is located. If we increase the time or hours that we are watering, what we will achieve is to wet a larger area of soil or saturate the lower layers of the soil, but this does not mean that the plant will have a greater availability of water.

It is therefore better to continue irrigating for the same amount of time but with much more frequent irrigations in high temperatures, so that the same area is always wet. Another reason for increasing the frequency of irrigation is that with high temperatures, water evaporates more quickly, so it is necessary to increase the water supply to our crops.

One way to make better use of irrigation water is to apply EDYPRO HUMECTANTE to achieve wide bulbs with an optimal distribution of irrigation water in the soil particles and retaining it, so that the plant can take it according to its water needs.

2.-Against high temperatures, another recommendation is to protect the plant from the sun. If the crop is grown outdoors, whether fruit or citrus trees, there are no sunshades for this. Therefore, it is recommended to provide magnesium to increase the level of chlorophyll in the leaves, increasing their resistance to excessive radiation. In this case, EDYPRO has developed EDYMAG, a magnesium deficiency corrector that is easily assimilated and offers very visible results in the crops, as magnesium increases the level of chlorophyll and the leaves of the crops are more resistant to sunburn.

In addition, the leaf mass of the crops, with the application of EDYMAG, becomes more vigorous because the photosynthesis potential increases, which results in a better protection of the fruits from the “spotting effect”, burns that appear on the fruit due to an excess of sunlight.

3.- In crops under shelter, the “bleaching” that reduces the sun’s radiation and the stress it causes to the plants is essential.  When the light intensity and temperatures drop, this bleaching is washed and removed and the greenhouse is left with sufficient light.
