Green Industry Native Plant Survey

Rutgers Cooperative Extension of Monmouth, Cumberland, and Middlesex County have developed a brief needs assessment survey to gain a better understanding of the educational materials and technical resources that are needed in the nursery and landscape industries to help promote the production and marketability of native plants.

If you operate a nursery, greenhouse, or landscape business in NJ and grow native plants (or have an interest in starting to grow native plants), please fill out this 5-minute online survey to help Rutgers Cooperative Extension develop resources and programs to support our green industries.

Crop progress: Drought stress continues

Drought conditions continue to stress crops in South-Central counties and a significant portion of northern NJ. Although the US Drought Monitor indicates conditions are only in the abnormally dry category, local conditions along the Pilesgrove-Upper Pittsgrove border west of the Salem River and adjoining areas of Gloucester County are experiencing moderate drought conditions in some fields; but not others due to the sporadic precipitation paths of recent storms. All stages of corn and soybeans in affected fields are showing signs of yield reduction due to disruption of pollination and seed set.

The USGS Below Normal 7-Day Average Streamflow Condition Map more accurately reflects a moderate hydrologic drought (darker orange colored area). A significant portion of the region has seen below normal precipitation for the past seven days. A streamflow which is less than the 25 percentile is considered below normal. The darker orange shaded areas of South-Central NJ of the USGS map represents 6-9 percentile stream flow activity.

below normal 7-day average streamflow condition map

 

 

Another way to observe increasing crop stress is to look at the cubic feet per second discharge of streams in the area since planting season. As seen in this graph of the Maurice River at Norma, NJ, current stream level discharge is well below the median daily discharge value over the past 88 years.

July Pest Scouting Nursery, Landscape, and Christmas Trees – Key borer and scale insect control timings

Pest Scouting – Please refer to these documents for a full listing of insects pests for your area corresponding to growing degree-days (GDDs). 

Quick look guides for July (Borers and Scales) and (All other) 

Contact if seeing insects at different times: twaller@njaes.rutgers.edu (or call the Cumberland County Extension Office – 856-451-2800)

The following key groups of pests will be active, vulnerable, or otherwise treatable during the next month throughout most of NJ. Here, scale insects and borers with key life stage events during the 1000-2500 GDD timeframe are discussed. Note there are many other insect pests present this time of year so please view the pest scouting guides above for your particular needs.

Projected GDD50 Accumulation as of July 13 2022 Note: Growing degree-day values utilize daily average air temperatures with a minimum temperature threshold (a.k.a. ‘base’) of 50F = GDD50 (max. temp. threshold set at 95F). These values are accumulated from a biofix date, such as January or March 1st in the NE USA. Provided GDD50 are scouting ranges and should be truthed.

Sign Up By June 30 to Receive the 2022 Census of Agriculture

Sign up to be counted, agcensus counts

Agricultural producers who did not receive the 2017 Census of Agriculture and do not receive other USDA surveys or censuses have until June 30 to sign up to receive the 2022 Census of Agriculture. USDA’s National Agricultural Statistics Service (NASS) will mail ag census survey codes for responding securely online to every known U.S. producer this November. Hard copy questionnaires will follow in December.

The ag census, conducted for over 180 years, remains the only source of comprehensive and impartial agricultural data for every state and county in the nation. It includes every operation – large or small, urban or rural – from which $1,000 or more of agricultural products are produced and sold, or would normally be produced and sold, in the ag census year.

“The Census of Agriculture is a complete count of U.S. farms and ranches and the people who operate them,” said Bruce Eklund, state statistician of the USDA’s National Agricultural Statistics Service (NASS), New Jersey Field Office. “Every response is important. The Census of Agriculture is only taken once every five years and documents the value of America’s rural and urban farmers and ranchers. When it comes to Agriculture, people seek information about the local level. Help us document the importance of agriculture in your area.”

On the NASS webpage, producers can also access frequently asked questions, explore past and current ag census data, access tools to help spread the word about the upcoming ag census, learn about ag census special studies, and more.

NASS builds its distribution list for every Census of Agriculture between and during ag census through the official sign-up webpage and multiple National Agricultural Classification Surveys. To learn more about the 2022 Census of Agriculture, visit their website or call the NASS New Jersey Field Office at 503-308-0404.

NASS is the federal statistical agency responsible for producing official data about U.S. agriculture and is committed to providing timely, accurate and useful statistics in service to U.S. agriculture. USDA is an equal opportunity provider, employer and lender.
