That fertilizers stay clear of the application of chemicals which often not only leave the vegetables and fruit tasting far better, but help the planet. Many people prefer healthy living along with looking to stop on ingredients that have chemicals. Husch & Husch Firm's ferlizers are not dealt with chemically. His or her fertilizers may verify for ones yard when they assistance in improving your libido in the garden soil. His or her products will not include creature excrement and so are welcoming within distributing when they include reduced odour.

Natural fertilizer and Soil fertilizer test will not discharge vitamins and minerals since easily since a few man made fertilizers, which often stops over-fertilization associated with vegetation, bouquets or even produce. Natural fertilizers usually tend to separate vitamins and minerals far more slowly, featuring vegetation a comfortable circulation associated with pure vitamins and minerals that boost their own growth.

Subject: Nutrient Management in Times of Drought: Summary Links & Series Feedback!

A big Thank You to the knowledgeable experts and panelists who participated in the Nutrient Management Series over the past five months!

Please take our two-minute survey to let us know what was helpful or not; and what information *you* would like to see in the future to better manage soil nutrients and the reduced water supply.

A lot of great wisdom was shared during the series, and so below are some quick links to access the highlights. This was a challenging yet fun pilot to bring the complex topic of soil management to a broader audience online, so of course there is more we can cover. Please take our quick survey to share your thoughts.

If you haven’t heard of the three-part series until now, check out the project background and vision. And join the Group for future series!

With subsurface drip, it’s a mistake to not consider gopher control. It might not be a good idea to install drip in an area with a gopher control problem. Choose an area where you don’t have a huge gopher pressures, if possible. Flood irrigation can help control gophers. I would recommend to put in checks along with the subsurface drip system, just in case you need to flood to control the gophers. Drip systems have an upfront cost that can take you three years to pay off, so you want to make sure your drip system doesn’t get destroyed!

We just started seeding the rangeland this year. We can’t use no-till drill because of terrain so we broadcast the seed. We bought perennial sub-clover and grass seed, broadcasting ahead of animals, which we hope will help bury the seed and fertilize with manure. Subclovers don’t germinate well in the first year. We’ve seen some stuff come up, but it may be a couple of years until we see the benefits. The stuff coming up now we will let go to seed and keep the animals from grazing it. Next year winter/spring we’ll bring back the animals again.
With the drought issue, we have to move our animals more often. We usually get 50 plus inches of rain here and this year we’ve got 20. We’re debating if we want to cut hay at one of the properties we graze. But we have a unique situation with grazing land of more than 2000 acres, and we only have 20 cows and 100 sheep, plus a lot of residual stockpiled forage.

Speaking of alfalfa... With alfalfa needing about 4 acre feet of water for full production, the question becomes: If you’re relying entirely on surface water how are you going to manage the water you have available? Should you divide it up and give your alfalfa a tiny drink at every cutting? Or is it better to get more water on earlier in the season? I’ve seen some research that suggests that midseason cutoffs are likely to maximize yields, meaning that full irrigations for portions of the early season could be better than partial irrigations over the whole season.


·Also, one of the biggest issues in alfalfa is the stem nematode, a microscopic worm that has been expanding in its range. It feeds on the above ground parts of the crown, and creates entry wounds for secondary pathogens. It disappears after the first cutting but the first is the most productive. Growers should be careful to wash equipment well when moving from one field to the next.

Subject: UC cost of production study for alfalfa on subsurface drip irrigation, including pics

I want to share a new study we just finished looking at the cost of production for alfalfa on subsurface drip irrigation. The study provides information on the costs for establishing and producing alfalfa for six years using this system. Take a look here. Let me know if you have any questions about the study.

Additionally, I want to share two photos (number 2&3 below) of the same alfalfa field in Yolo County, which went dry last summer due to no water allocation, but the stand recovered once it started raining again in the fall. Alfalfa is highly drought tolerant because the plants will go dormant without water, but then of course there's no yield.

We’d be interested in hearing from others, but thought we’d add to the discussion of subsurface drip irrigation (SDI) in alfalfa. The UC ANR 2014 cost study for SDI in alfalfa is an economic analysis, not a feasibility study. Many of the growers who are implementing SDI in alfalfa are in the San Joaquin Valley or Imperial Valley, as well as the Sacramento Valley. The only region where SDI seems more problematic is the Intermountain region where rodents are a bigger issue, and the potential yield gains are less due to the short season.

SDI makes available essentially an infinite number of possibilities for irrigation scheduling, compared with check-flood in alfalfa (or in furrow systems for row crops). It minimizes evaporation. Check flood is limited to 1 or 2 irrigations (of about 4-6” each) per harvest period in most cases. Farmers have used a wide range of irrigation schedules with SDI in

In organic alfalfa production, growers who are fertilizing with chicken manure or other organic ammendments need to make sure they have adequate P levels. If soils are really deficient, growers should probably not start out as organic, because with organic alone they will never catch up in a P deficient situation. If growers are looking for more information on organic alfalfa production there is a great UC cost of production study for both subsurface drip and organic alfalfa. Worth checking out.


For alfalfa, subsurface drip irrigation (SDI) can increase yields by 30% in the Yolo county area. However, there is a huge cost to put in a drip system. Initial installation costs could run between 1500-1800$/acre. In the end it can pay off, particularly in sandy soils. Rodent control is also a consideration as it can be expensive. Rodents damage the drip lines and repairs are pretty costly.

Subject: Vision & background of the Soil Management Series & Forage Crops kick-off!

You’ve probably seen the posts over the past several months about soil nutrient management in times of drought. Check out today’s blog where we sat down with our UC SAREP partners about the background and vision for this series, ways to flatten the learning curve regardless of experience level, and how you can participate. -- http://wp.me/p3xDpS-200

Today is also the kick-off for the next segment of the series: Forage Crops! More to come later today…

Subject: Announcing Moderator Line-up: Forage Crop & Nutrient Mgmt in Times of Drought Virtual Field Day

Hi all,

Next Monday (4/6) kicks off our next Nutrient Management Virtual Field Day series, and the topic is forage crops!

We'd like to introduce you to our expert moderator line-up, and please join us for the conversation next week.

And remember, the format of the forum is that we’ll release a Q&A from our moderators every day or two, and you’ll have a chance to post a question or comment. Or, better yet, share your experiences and tips you have found.

We have all our moderators “on call” for almost two weeks to keep the conversation rolling and help you get answers. So chime in when you can!

If you have questions or ideas for the series, get in touch: rmurphy@ucdavis.edu
