Subject: Seeking Garden Symphylan Guidance

Hi all,

My name is Grayson, myself and three others started a diversified fruit and veggie farm in Placerville CA this January.

We are learning that we have a Garden Symphylan (GS) infestation in parts of our veggie field. I have found them on the roots of crop plants, as well as lured them with potato slices. They have seriously damaged patches of direct sown spinach, killing or stunting plants just after germination, seems to be stunting growth on transplanted parsley and currently are attacking our direct seeded squash as it germs, killing some before they break the soil surface. It is presenting in patches, and is especially hindering direct sown crops. I have found them in numbers up to five per plant in the bad spots, and 15+ on some of the potato lures. It's definitely impacting our yields and causing us to worry about the suitability of the site.

After reading though some literature on GS it

So, I recall attending a Soil Food Web seminar back in 2002 in Santa Cruz, with Elaine Ingham, and we went to UCSC farm/garden, which has major symphylan infestation at the time, and Elaine claimed that the soil was "out of balance", and that symphylans only are primarily fungi feeders, which didn't match my, or Jim Leap's observations. I think symphs are opportunistic, feeding on fine plant roots and/or soil fungal mycelia, as the opportunities arise. Both Jim's and Mike M's experience underline the idea that incorporated cover crops provide large boost to population numbers, likely through symphs feeding on fungi, as well as the ease of transport in the upper layers of the soil, with so many transport routes (roots?) in the top soil layer from decaying cover crop residue. Because they migrate vertically in the soil profile, their population numbers can be pretty random, as Jim L mentioned. it's

Subject: Soil Test Interpretation

My fertilizer strategy is to satisfy my banana crop nutrient needs trough weekly fertigations. My crop looks healthy and vigorous but my soil test results show that some nutrients (P, K and S) are below adequate. Can this be expected since Im not trying to build up nutrient reserves but satisfying inmediate nutrient needs? What does "adequate" in a soil test really means? that my soil already has enough nutrient for the whole crop season?

Thanks, Luis

Subject: Discussion on Biostimulants market in Florida


I would like your inputs on the following queries:

1. Do you use biostimulants? If yes, then what products do you use?

2. Would you like to use biostimulants? If yes, then what kind of biostimulants would you prefer?
3. Do you think Biostimulants are healthy for soil ?
4. If you are considering to use biostimulants then, what details do you need before starting to use the product?.
5. What are the major issues that arise during growing strawberry, tomato and other crops?

We saw your post requesting info from the farming market in Florida... 1) 99% of this community is in California, and 2) I see that you are a market research firm, which is not a good fit for this forum. May we suggest you contact farmers and ranchers in Florida directly. Best of luck.

Subject: Liquid fertilizer vs. compost or manure

A question for organic orchard growers: are you more likely to use compost or manures to supply nitrogen, along with a cover crop, or apply liquid nitrogen in your irrigation water? A friend has been giving me dried horse manure from his operation, and I have also purchased compost. I'm trying to decide if I should buy a manure spreader for the dry material, or look into a pump system to apply liquid fertilizer. While it would be easier to calculate the application amount with the liquid, I could be getting other benefits with the compost or manure. Thanks for any input.

We use cover crops, compost and bagged fertilizer on most of our trees, although some of the big older trees do not get all of this every year because their root systems are deep enough and the soil is built up enough. We do some foliar sprays and fertigation too, but mostly with seaweed and fish and micro-nutrients as needed. Although we hated to buy a manure spreader because we only use it once per year, we couldn't find one we could borrow or rent and with an orchard the commercial spreaders won't fit under the canopy, so we bit the bullet and bought one. It would be really great if regions with small growers could get together to share equipment like this.

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 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.

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.

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).

Simple but yet a ground-breaking innovation by earth sciences published in a recent website ( , 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.


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 estimation of the number of microbes by traditional laboratory methods is
