Correcting nitrogen deficiency

Correcting nitrogen deficiency in beans

Recently we found ourselves correcting a nitrogen deficiency in our green beans.  They were beginning to turn yellow throughout the entire plant, meaning we have a nutritional deficiency.

To ensure we correctly identified the deficiency and made the right correction, we went to the MGC book.  On page 147 of the Mittleider Gardening Course shows us a general yellowing of the entire plant is a nitrogen deficiency.  It calls for a correction of 1/4 ounce per linear foot of nitrogen to be added.  The nitrogen should be worked into the soil and watered into the soil.

Urea is available locally, 46-0-0, so we will use it as our form of nitrogen.

What caused the deficiency?

It is normal to see deficiencies in your garden.  Some plants use more nitrogen than others, making them more susceptible to some form of nutrient deficiency .

In our case these beans were started in some recently mixed sand and sawdust in a grow box.  The natural decomposition  of that sawdust used up the available nitrogen.  One application of the urea 46-0-0 was enough to bring the beans green color back.

Recovery time

It may take a week or two for plants to recover if you have correctly identified the problem.  If after one week no improvement is seen then look for other possible causes.  As always, it would behoove the gardener to refer to the Mittleider Gardening Course book.

Germination in the seedling flat

This morning I watered the seeds in the seedling flat that I planted less than 48 hours ago.  Once watering was complete I peeled back the burlap to check on them and was surprised to see germination already!   Now that I have germination the burlap will be removed.   I will still water through the burlap to help protect the seeds.

From left to right in the picture that has currently germinated you will see arugula, kale, peas and the beginning of my beans.  I will need to build some additional seedling flats so I can bump up the seedlings as they grow and become confined.  These will be planted in our grow boxes and will have an in garden green house built over them to extend our gardening season.
