Subject: Nutrient Mgmt Virtual Field Day: Monitoring nutrient and moisture levels to maximize productivity

Welcome to the Nutrient Management Virtual Field Day! Here is our first topic to kick things off:

Clearly, in limited water situations, monitoring your nutrient and moisture helps maximize productivity. What are your top tips for farms to accomplish this? What monitoring practices do you use? How did you adapt your monitoring practices for the drought?

Below, our featured panelists will respond, and then we invite YOU to share any ideas, tips or questions you have as well.

For bios of our panelists and to learn more about the Series, check out the Nutrient Management Solutions group. This Nutrient Management Series in Times of Drought Series is a collaboration of UC SAREP, FarmsReach and Sustainable Conservation.

Hello Franz thanks for quick http://feedback.We are tracking infiltration depths with GPS moisture probes wirelessly connected to the matched Software package to track improvements. Using either the frequency drivenC2A0 Hydrosmart water systems or the ESP frequency driven water systemsWater Infiltration root zone depth is faster and deeper. On almonds we are seeing approx. 18" deeper penetration infiltration. We will be in Phoenix at the Irrigation show this week. If you are wondering where to get more info go to http://www.hydrosmart.com.auC2A0 Or http://www.customizedwatersystems.comWe own USA distribution support on these non flow restricted water systems. The systems creates scalar energy wetter water with hydrogen bonds broken. Wetter water soaks in the ground faster and breaks up scale into usable root nutrients in high TDS water. Units are all Green http://performance.We are dropping 3 more ESP... Read More

Subject: New cover cropping videos and climate change paper

Hi Folks,

Below are YouTube links to my two newest, 8 minute cover cropping videos that I thought might interest you:
It was fun to present the first video last night at the CCOF Central Coast Chapter meeting in San Juan Bautista. It was followed by a good discussion.
In my presentation I highlighted 1) a recent review paper (Agron Sust Dev 37p4) on cover crops and climate change, and 2) my recent opinion paper (HortTech 27p151) that includes some alternative cover cropping approaches (i.e., juicing shoots for liquid fertilzer, etc.). The PDFs of the papers (see citations below) are attached for you to download and enjoy.

Subject: Looking for organic manure in the Santa Cruz Area

Looking for advice - Hello! I am looking for a grass fed dairy operation in the Santa Cruz California to buy manure from to make compost for an organic farm operation. Only interested in chemical/hormone free operations. Does anyone have advice on operations that maybe interested to sell their green? Thank you!

Thanks Collette! I will e-mail you now. I would also love to hear from any others, as we are looking for multiple sources and also aged manure and bedding (from chemical free/hormone free operations).

Subject: THE MICROBIOMETER: A NEW, INEXPENSIVE AND EFFECTIVE WAY OF KNOWING MICROBIAL BIOMASS FOR FARMERS .

Simple but yet a ground-breaking innovation by earth sciences published in a recent website (http://www.microbiometer.com) , the microbiometer promises to be a huge step towards enhancing every farmers ability to better understand the soils biomass so that informed decisions may be made concerning the soil nutrition level.

BIOMASS

It is well documented that Microbial Biomass (MB) is an important indicator of soil fertility. Microbes are important to the health of the soil because.: 1) they fix nutrients in a form that makes them available to plants; 2) they facilitate the uptake of nutrients and strengthen the resistance of plants to plant predators and infection; 3) they reduce water loss and erosion by binding the soil particles which provide soil structure, and by supporting plant growth.

THE MICROBIOMETER

The estimation of the number of microbes by traditional laboratory methods is

Cal Poly SLO student project is seeking participation from San Luis Obispo County growers to assess crop and pre-consumer food waste generated within the county. If you know of growers who might be willing to contribute, please forward the link to them. (If you are a processor or distributor that generates food trimmings, please also fill in applicable info in the same link the best you can.) Respondents replying by August 10 will be entered to receive a delicious meal at Ember Restaurant in Arroyo Grande! Participation is greatly appreciated, please use the link below:

Subject: Food Safety Regional Lead for Tulare, Fresno, Madera, and Merced counties

Good Morning Ya'll,

My name is Jacob Roberson and I am the Food Safety Regional Lead for Tulare, Fresno, Madera, and Merced counties for a non-profit organization called Community Alliance with Family Farmers (new to Fresno area). CAFF is well established all over California except for the Central Valley which is where I am based out of (Fresno to be exact). I wanted to use this post as a source to contact farmers who are struggling with food safety and cannot afford to hire an outside consultant to come to their farm, perform assessments, help with documentation, and get their farm ready for a 3rd party audit. I perform the same duties as an outside consultant but my service is no cost to the farmer. CAFF is a non-profit organization looking to better food safety standards and procedures practiced on small farms / farms at a disadvantage (financial hardships, language barriers, new farmers, etc.).

Subject: Two Vidoes on Sustainability Challenges in Organic Agriculture

Hi Folks,

Below are links to two 5 minute, thought-provoking videos that I made and presented at a symposium titled "Sustainability Challenges in Organic Agriculture" that I co-organize for the annual meeting of the American Society of Agronomy in Phoenix, AZ, last month. The first video is focused on NITROGEN FERTILIZERS and SOIL FERTILITY MANAGEMENT in high-input, organic vegetable systems like those that are common in the Central Coast of California. The second video, with two coauthors who work at the USDA-ARS in Beltsville, MD, is focused on PEST MANAGEMENT challenges especially with PERENNIAL WEEDS.

Subject: Understanding Nitrogen in Organic Tomato Production

Dear Farmers, knowing whether the plants have enough nitrogen at each growth stage can be very challenging because multiple amendments are often added to grow organic, fresh market tomatoes, such as compost + sea bird guano + liquid fertilizers. A small research team at the University of California are undertaking a study to demystify this information. Through this research, we will determine the nitrogen demand in tomatoes and how much nitrogen is made available by each amendment, for each week over the season. We would love to know what amendments you are using so that we can include them in our study.

Organic Tomato Nitrogen Study

Please help us make this research most relevant for you by completing the survey. Results from this research will be made publicly available. Thank you so much! Margaret

Subject: Vermicomposting

Have you tried vermicomposting? What was your experience like?

Vermicompost is the heterogeneous product of the decomposition of food, vegetable, and plant material along with vermicast (an earthworm’s by-product of the breakdown of organic matter). Vermicompost is an excellent organic fertilizer or used as simply a soil conditioner, as it is rich in readily-available, water-soluble nutrients. Vermicomposting also has various commercial uses besides fertilizer, such as its ability to function as sewage treatment. With all of these benefits, one might perceive vermicomposting as a daunting process, yet with a bit of research and knowledge, the system can be simple to maintain once established. There is an entire internet community with amazing how-to guides. Here is one example: http://lancaster.unl.edu/pest/resources/vermicompost107.shtml
