The first signs of a successful watermelon patch appeared in late July.
Not a miracle harvest.
Not a field suddenly transformed into a green paradise.
Just healthier vines than Eli had expected under conditions that were damaging nearly everything around them.
The stone-treated rows held moisture somewhat longer than the exposed comparison bed after watering, but the difference varied with the weather. Some stones became uncomfortably hot during the afternoon, and Eli learned to keep them away from young stems and leave enough space for developing plants.
The organic mulch also helped.
His records suggested that careful soil coverage reduced rapid surface drying, especially during windy periods.
But the most important difference appeared at the lower end of the North Bed.
The soil there remained damp even when the rest of the plot began drying.
Eli checked it repeatedly.
He recorded dates.
Measured temperatures.
And compared conditions after periods without rain.
The readings confused him.
The lower bed wasn't receiving more irrigation than the others, yet its soil retained more moisture.
One afternoon, Ms. Alvarez returned with a conservation district technician named Nora Kim.
Nora was thirty-six, practical, and accustomed to explaining soil and water problems to farmers who didn't always appreciate being told their assumptions were wrong.
She worked with a local conservation program that helped landowners evaluate erosion, soil management, drainage, and water use.
Sarah had given permission for the visit.
Nora examined the garden with interest.
She didn't laugh at the stones.
But she didn't congratulate Eli simply because the plants looked good.
Instead, she asked questions.
“How much water have you added?”
Eli opened the notebook.
“Here's every time I irrigated.”
Nora nodded.
“Good. How did you measure it?”
He showed her the marked containers used for his small test plots.
She examined them.
Then pointed toward the lower bed.
“Have you checked whether water is entering this area from somewhere outside your irrigation?”
Eli nodded.
“That's what we're trying to figure out.”
She looked toward the old cottonwood stump.
Then examined the topography.
The land sloped gently toward the south.
