Sun exposure and shade necessary for guardian livestock animals and their flocks

Many landowners have added on pasture fowl in the last year and realized the need for pasture protection from owls, eagles, and hawks; and minks, skunks, and foxes. Many have gotten guardian animals. These animals range from great pyrenes to donkeys to lamas.

The rule of thumb. When the heat and sun are high in a cloudless sky, shade is essential to prevent dehydration of all livestock including guardians and regardless of species or breed; or the ancestral climate where the animals originated from. If it is too hot and too bright to be outside wearing a winter coat and sunglasses, make sure animals have access to sun-shelters. This is especially relevant now as we enter a week of high temperatures without precipitation. Recently sheared animals are at risk of sun burn and light skinned, light eyed animals are at risk of sun blistering on eyes, noses, and lips. As fly season has begun, this is a critical distinction. Fair-skinned animals with lighter eye pigment and lighter pigment on nose and lips are more prone to pink eye and other eye infections.

Tree cast shade is excellent as long as the shade cast direction is into the enclosed area from high noon to sunset. In the absence of natural shade cast into the pasture by high noon, man-made shelters need to be provided. Consider modifying fences to allow animals to reach tree lines. Man-made shelters should reflect sun and must allow for air flow. In the same manner a pop-up tent would provide shade for humans in outdoor recreation settings. The size of the shelter must match the size of the herd lying down with social distancing space included. This may require splitting herds up to match shelter sizes.

Non-cattle, non-equine livestock guardian shelters. Round bale feeders covered with a metal gate and tarp or plywood are a quick emergency solution for single unfettered dogs, rams, and other small statured guardian animals as long as they can easily climb through the spaces. Usage has to be monitored to make sure the livestock being guarded are not crowding into the same shaded space and collars should be removed to prevent getting caught on bolts. These types of temporary shade structures should not be used for multispecies groups. A better solution is calf huts or home-built a-frames.

For large herds (excluding cattle and equine). Multiple shelter’s will be needed and again, herds may need to be split into groups. If you do not have a barn or lean too shed, flat bed wagons tall enough for sheep, lambs, goats, geese, and chickens are another quick solution. In pastured situations, these mobile shelters must be moved regularly to avoid fly larval build up and bacterial contamination of teats in nursing dams. Stationary shelters should be cleaned regularly for the same reasons.

Prevent young stock injury. Overcrowding fights for space in shade will lead to lamb, kid, chick and calf injuries. Dogs and donkeys will naturally protect their ‘resting space’. Chickens and other fowl should not be crowding into the same space as the guardian dog or donkey. As your herd expands, provide more shade. If nothing else, even round bales set out along the outside of the fence so that their shadow casts inwards will provide some shade from the effect of high sun and high heat.

Monitor water availability, quality, and temperature. When animal’s crowd water sources, contamination is inevitable. As daily temperatures increase, watering systems need to be cleaned daily and covered to lower the temperature of the water. Water temperature influences rumen and gut function and just like humans, animals don’t want to drink super warm water. As the temperature of the water goes up, consumption goes down. For man-made watering systems containers, provide water shade when water temperatures are staying above 77°F.

Make sure all animals and fowl have access to plain white salt. In single species herds, specialized salt blocks containing other minerals should be used that are species appropriate. Remember, salt block mineral formulations for cattle are not always safe for sheep and goats. In mixed herds, during high heat, make sure animals have daily access to choose from plain white salt and iodized salt blocks.

Soil residual herbicides and lack of precipitation

May 17, 2021

Dry surface soil conditions

Soil residual herbicides require precipitation to activate

Salem County. Surface soil conditions are quite dry across much of the acreage planted in the last two weeks. While their is adequate moisture in the rooting zone for corn and soybean germination, without a half inch to inch of precipitation or irrigation, soil residual herbicides applied to manage herbicide resistant weeds and other annuals will be slow to activate. Monitor fields for signs of common lambsquarters and amaranth as air temperatures rise this week into the 80’s.

Precipitation departure from normal for South Jersey counties

As planting season progresses, producers in south Jersey are keeping an eye on soil moisture. While year to date precipitation in inches is near normal for most of the state, thirty day and seven day departure from normals require closer attention. As do feed budgets for those who purchase corn, wheat, and soybean meal due to the large portion of the grain belt that is experiencing significant drought at the beginning of the growing season.

Soybeans planted already? Weather and preherbicide considerations

Early morning soil temperature

Soil temperature, Woodstown NJ. April 22

Some producers took advantage of their efforts to fit fields last week and have planted full season beans at the time of this post. Soil temperatures were above 55ºF to 60ºF at planting. Peas and potatoes are also planted.

A cold front last night coupled with gusty winds dropped surface soil temperatures below 50ºF in the Woodstown area.

Should pre-emergences go on at this temperature? Soybeans and other Fabaceae seeds like peas will swell and germinate within twenty-four hours of planting if there is adequate soil moisture. But under cool conditions, twenty degrees below ideal (>70ºF), don’t expect to see plants come out of the ground until soil temperatures warm up. Which is forecasted to gradually occur over the next ten days. That is plenty of time to get preemergent herbicides on before crop and weed seeds germinate. If the weather cooperates. Which at this hour, looks favorable for application Friday and Saturday mornings in Salem County.

The current forecast for the Woodstown, NJ area is for less than an inch of rain Saturday into Sunday morning. Enough to activate preemergent herbicides. But locally heavy downpours are possible.

Herbicide injury is more likely on cold, very wet, coarse sandy soils until soils warm. Cold wet conditions that slow emergence of soybeans ,and after a root and shoot inhibiting herbicide have been applied, can result in herbicide injury. Slower emergence means more time for the herbicide to be absorbed into emerging shoots and roots. What we don’t want is open furrows, on low organic soils as this only increases the likelihood of injury while soils are cold and wet.

Residual, pre-emergent to the weed seed germinating. Some soybean products like sulfentrazone can be applied a month before the crop is planted but warn of significant injury after excessive rainfall or in poorly drained soils. Others specifically state application up to fourteen days prior to planting; or apply after planting. There is somtimes a two-week application restriction between pre-plant incorporated; pre-plant surface timings; and the allowed after planting application on the same label for the same active ingredient for crop safety purposes. Others have no such restrictions. Before spraying, consider the forecast, current and future soil conditions, and read through the herbicide label as this information is not always in the same paragraph.

Why the forecast after planting matters: Heavy rainfall can push pre-emergent root and shoot inhibiting herbicides below the weed seedbank germination zone. Defeating the primary purposes of this application to prevent weed seeds from germinating. For weeds resistant to the post herbicides available (palmar amaranth, common ragweed, marestail) few options remain. Conversely, we need rainfall to activate soil residual products.

No application before weeds germinate is just as concerning. Emerged weeds are not controlled by pre-emergence herbicides. We don’t want soil temperatures to reach the optimum for weed seed germination before application. Common ragweed and common lambsquarters will start germinating after soil temperatures rise above 50ºF. For Palmer Amaranth and other pigweeds, anticipate weed seed bank to flush when soil temperatures are approaching 60ºF degrees; and negligible when day and night time temperatures continue to fluctuate below 50ºF.

A spray tank’s last check list visual aide for corn and soybean weed management

Back in March, regional weed extension professionals discussed creating a visual aide chart for herbicide selection for the big three problematic weeds (palmer amaranth, common ragweed and marestail) in corn and soybean.

Below are two url links to “A Spray Tank’s Last Checklist in Soybean“; and “A Spray Tank’s Last Checklist in Corn” courtesy of Mark VanGessel, Extension Weed Specialist, University of Delaware Research and Education Center.

Note, these are not meant to replace anything extension has available already, rather to supplement and be coupled with herbicide resistance charts in the Agronomy Guide and the 2021 Mid-Atlantic Field Crop Weed Management Guide noted in this MARCH 5, 2021 post by Thierry Besancon, Rutgers Extension Weed Specialist

These supplemental charts are meant to be used as the spray tank is being filled, to ensure the right products are in the tank – thus the title “Last Check Chart”. These are not meant to be comprehensive for all herbicides and weeds, rather what extension weed experts in our region are recommending for the BIG 3 in corn and soybean. Always refer to the individual product label for weed and crop height and growth stage restrictions.

Ultimately plans are to have a wall-chart that can be distributed next extension season.
