  What a Difference a Day Makes!

Well, OK, actually two days. These two pictures were taken about 48 hours apart so you can see that bloom progresses rapidly when the weather is warm. This is also a young orchard exhibiting "youthful vigor". It is a few days ahead of our older orchards.

Feb 12, 2014

Here are rows very close to the previous photo and of the same two varieties, Nonpareil (most blossoms) and Fritz. Nice day today, the bees were very active. I'm sure each of the few open blossoms was visited several times.

First Fog of Winter 2013-14

The rain we had over the last week or so (only about 1") has provided some badly needed drought relief and has set up conditions for our first fog of winter. Typically November and December are our foggy months.

Note that bloom is still a week or so away.

26 Feb 2013

 This image was taken almost one year ago on Feb 26, 2013. The bud development looks similar to the next image taken today, Feb. 10, 2014.

It appears that this year the bloom will be about two weeks earlier than it was last year.

Earlier bloom timing can mean more risk of frost.

The bees are in place and appear anxious for the blossom festivities to be underway.

Machine shaking mummies is the alternative to hand poling. It is more economical when there are a lot of mummies, if they are difficult to remove, or the trees are so tall that poling is impractical. The severity of the shake can be adjusted to match the energy required to remove the nuts. Usually winter shaking is less vigorous than at harvest time. This year we are lucky that the nuts are easily removed despite the dry conditions. Often nuts are difficult to remove unless they are saturated with water from rain or fog.

Poling Mummies

January is the month to remove mummies (nuts that were not removed from the trees at the most recent harvest).  Mummies are the overwintering site for Navel Orange Worm (NOW). Mummy removal is the most important worm control activity of the year. In orchards where there are not too many mummies and if they are easy to remove, hand poling is an economical approach. Sadly, notice the lack of weed growth here. Since my rainy day post of November 20, 2013 we have had no rain, and none is in the forecast. The awful "D" word is heard every day, Drought. More on that later.

Elvauating the island near Hana...too steep for almonds

Where have I been? Your Almondfarmer recruited the family to help evaluate Maui as a place to grow almonds. Unfortunately we found the island to be wholly unsuitable for almond farming. Steep terrain, sea breezes, lack of chilling and nearly continuous pleasant conditions are just some of the impediments. The trip was not a total loss however since we discovered it may be a nice place to vacation and we hope to return some day with less focus on work.

RAIN!

Finally! Rain, where have you been?!

Drought Stress?

I mentioned in my most recent post that we are continuing to irrigate due to the lack of rain. But not all appearances of drought stress are necessarily due to lack of water. Although the trees in this orchard appear thirsty, they are really dropping leaves due to a late infestation of Rust disease (a fungus).

Rust

Rust disease has been a challenge during the last few years. This year, one application of fungicide kept the disease down before and through harvest. This late season infestation is a reminder that we will need to be on the lookout for it again in 2014.

Drip Irrigation with well water

It is almost mid November and we are still irrigating! We've had no rain and the trees continue to use water during the mild days (70's) we are having.

The drip tubing was secured at the top of the berms to be safely out of the way during harvest.  We leave the tubing there until spring. This keeps them secure while we sweep the mummies to where they can be destroyed by a mower.

Where we do not have access to well water, some of the trees are experiencing stress and beginning to drop leaves. This is the kind of leaf drop we might want from cold temperatures this time of year, not from lack of water. We definitely need rain!

Getting ready for a pre-plant fumigation with Telone. A lot of specialized equipment is involved. Fumigation reduces soil nematode populations and is important for reduction of Replant Disorder, an ill-defined soil condition that stunts new trees.

This is the GPS-guided tractor that will inject the fumigant into the soil. This rig is set up to "know" where each tree will be planted and apply fumigant in about a 10 ft. square at each tree site. This is a trial run and researchers will measure the concentration of fumigant surrounding each tree site to test the application accuracy.

Fumigants are tightly regulated and county biologists were on site to be sure all safety and regulatory requirements were being met. Pictured are Melanie Fisher (Stanislaus Co.), Kraig Williams (TriCal, Inc.), Anna Genasci (Stanislaus Co.), and Matt Gilis (researcher with TriCal, Inc.)

Almondfarmer with pilot Kevin Morgan Smith of Hawke Ag Aviation (aerial ag applications, Oakdale, 209-765-6762) next to the Cessna 150 that Kevin used to take me up for some aerial photographs. Kevin did a great job of flying, giving me lots of opportunities for pictures and made a smooth landing for a safe return

Aerial pictures allow us to clearly see weaker areas of an orchard. We can investigate what those areas will need to become more robust. In this picture a weak area is apparent where a hill top was removed. We can test what nutrients are deficient and supplement those areas.

WOO HOO! Almond harvest 2013 is complete for us as of today! No more nuts in the field!
