Irrigation for late season perennial fruit crops during drought conditions

As New Jersey continues to experience record low precipitation levels since September, the state Department of Environmental Protection has declared a drought warning throughout the state. It is important to note that the drought warning does not call for any mandatory water use restrictions or bans. However, if the drought conditions worsen, the state may implement stricter measures to prevent further losses.

We have received many questions from growers, most who have completed harvesting for the season, on whether plants should still be receiving irrigation. Our recommendation is to continue to irrigate plants until they defoliate. For perennial fruit crops, in the fall months flower buds are forming for the next year’s crop. The leaves that remain on the tree are actively working to photosynthesize, converting light into energy the plant needs to grow.

Once leaves begin to turn yellow, brown, and drop off, you can stop supplemental watering. However, if you are in a prolonged drought, as we are currently, there are some factors to consider. For perennial crops that overwinter, severe drought can compromise their ability to store sufficient reserves, which can lead to reduced vigor and potential losses during the winter. It can be the case that during periods of drought, plants may invest more energy into developing deeper root systems; however, over a prolonged period of time, persistent stresses can hinder root development, which can negatively impact water intake and nutrient availability. Additionally, whereas hydrated soils can buffer the penetration of freezing temperatures through the soil surface, dry soils do not offer the same protection, and freezing temperatures can penetrate deeper.

There are several strategies that can be adopted to mitigate the impact of drought on fruit crops.

  • A proper irrigation schedule that includes supplemental watering during growth stages can help alleviate drought impacts and stress. When possible irrigate trees through leaf drop, and avoid irrigation on warm days (60°F and higher).
  • Mulch can be applied around plants to help conserve soil moisture and reduce evaporation.
  • Soil sensors equipped with data loggers can be deployed in the field to measure soil moisture and water stress and report measurements to a computer or mobile device.
  • Regularly monitoring your crop for signs of drought stress including wilting, leaf curling and discoloration, and reduced growth, is critical for timely intervention and applying appropriate measures.

NJ Depts of Agriculture & Environmental Protection Allow Controlled Open Burning to Protect Crops

(Trenton) [On April 20, w]ith the state expected to experience cooler spring temperatures, the Department of Environmental Protection has agreed with NJDA Secretary Ed Wengryn’s request to allow farmers to do controlled open burning or use specialized torches known as smudge pots to protect flowering crops from damage beginning today, April 20, through Saturday, April 27.

Temperatures are expected to drop to the 30s or below tonight with varying winds through portions of the state. These expected temperatures follow warm temperatures in recent days. Damage from freezing weather now can significantly reduce yields of certain fruits and vegetables that are in the flowering stage.

The DEP and Department of Agriculture are allowing these steps to protect farmers’ livelihoods and to ensure that consumers will be able to enjoy an ample supply of Jersey produce later this year.

The DEP intends to exercise its authority and discretion under the Air Pollution Control Code, N.J.A.C. 7:27, et seq., and other applicable authorities to permit the following procedure for open burning or the use of smudge pots to assist farmers to protect their crops in low temperatures.

Farmers who believe they will need to conduct open burns and/or use smudge pots must provide notice to the DEP’s 24-hour Communications Center at 1-877- WARNDEP (1-877-927-6337).

Notification to DEP does not require the implementation of either technique but ensures proper procedures are followed should they become necessary.

If a farmer does not call DEP in advance but uses either technique, the farmer must notify DEP by 9 a.m. the following day. The farmer will be asked which technique was used.

Farmers must record the incident number provided to them by the Communications Center. The following information is to be provided:

  • Name of the individual making the decision to conduct the open burning/use of smudge pots and name of the farm.
  • Actual street address of the farm on which either technique will be used (no P.O. Boxes).
  • Telephone number of a contact at the farm.
  • Predicted temperature (in degrees Fahrenheit) at the agricultural operation when the technique will be used.
  • Wind speed anticipated when the technique will be used.
  • Predicted hours of open burning and/or use of smudge pots.
  • Materials expected to be burned.
  • At the time of the initial call to the Communications Center, farmers will be given an email address and incident number.

Within two days, they must submit to DEP via this email address the following information:

  • The DEP Communications Center incident number.
  • Ambient temperature (in degrees Fahrenheit) at the time the technique was used.
  • Actual wind speed at the orchard at the time the technique was used.
  • A statement verifying that all restrictions in the open burning or use of smudge pots were followed.
  • The New Jersey Department of Environmental Protection and New Jersey Forest Fire Service caution all farmers and agriculture businesses with respect to the use of open burning in high wind velocity conditions. Please take note that farmers are encouraged to utilize smudge pots for warming as necessary during higher wind conditions. Use of open burning when wind velocity is greater than 5 mph is strictly prohibited, may contribute to wildfire risk, and can carry significant penalties.
  • Smudge pots must be fueled only with either kerosene or No. 2 fuel oil.
  • Open burning can consist only of either the following materials: clean and untreated scrap lumber, felled trees, clippings pruned from trees and shrubs, hedgerows, or firewood. Absolutely no refuse, trade waste, tires or garbage of any type may be added to the authorized open burning material.

The New Jersey Department of Environmental Protection and New Jersey Forest Fire Service caution all farmers and agriculture businesses with respect to the use of open burning in high wind velocity conditions. Please take note that farmers are encouraged to utilize smudge pots for warming as necessary during higher wind conditions. Use of open burning when wind velocity is greater than 5 mph is strictly prohibited, may contribute to wildfire risk, and can carry significant penalties.
