Clovers and How to Grow Them

In Short

This comprehensive 1906 manual systematically examines every major agricultural clover, explaining how farmers across North America can successfully cultivate, harvest, and utilize them. Moving logically through soil preparation, nurse crops, threshing mechanics, and regional variations, it details the management of medium red, alfalfa, alsike, crimson, white, sweet, and yellow clovers. The text endures as a landmark guide to sustainable soil restoration, proving that integrating deep-rooting nitrogen gatherers into crop rotations provides a reliable, natural foundation for soil fertility and farm prosperity.

The Story

The book unfolds as a methodical blueprint for agricultural renewal, guiding the reader from universal soil principles to the specific management of distinct clover species. It opens by establishing the fundamental mechanics of sowing clover with nurse crops, explaining how seed depth must adapt to soil density—ranging from three inches in light prairie soils down to a mere surface dusting on stiff clays. From this technical foundation, the argument demonstrates how clovers naturally enrich depleted land. By capturing nitrogen and subsoil minerals, a healthy crop supplies more plant food than heavy applications of barnyard manure, saving farmers immense time and labor. Additionally, frequent cuttings of varieties like medium red and alfalfa serve as an effective, chemical-free tool for smothering annual and perennial weeds.

The exposition then surveys North American geography to map out where each species thrives. Medium red clover dominates the humid hardwood belt of the Midwest and the irrigated mountain valleys of the West, though summer droughts challenge it further south. As the treatise progresses to alfalfa, it counters contemporary misconceptions by showing that this deep-rooted crop flourishes far beyond sandy river bottoms if the soil is porous and free of acidity. The narrative details precise harvesting techniques required to preserve delicate leaves, recommending morning mowing, careful afternoon cocking, and specialized machinery like clover hullers or modified grain separators to winnow clean, marketable seed.

In its final chapters, the text explores specialized species adapted to niche agricultural environments. Alsike clover emerges as a long-lived alternative for damp or high-altitude fields, while soft, hairy crimson clover acts as an autumn catch crop in milder southern winters. White clover naturally choked out weeds in permanent pastures alongside bluegrass, whereas rugged self-seeders like Japan clover and sweet clover colonize abandoned, worn-out soils or steep railroad embankments, paving the way for future crops. The overall progression demonstrates that understanding each plant's distinct root habits, climatic limits, and harvesting requirements allows farmers to transform challenging landscapes into highly productive, self-sustaining agricultural systems.

How It Unfolds

Establishing the seedbed The text begins by detailing the mechanical methods of sowing clover alongside nurse crops, emphasizing how seed depth must adjust between three inches in loose prairie land and less than an inch on heavy clay.

Enriching through biology It outlines the chemical advantages of legumes, showing how deep roots pull nitrogen and potash into the soil more cost-effectively than hauling barnyard manure.

Mastering the harvest The focus shifts to field management, explaining how to mow after morning dew, stack hay safely against rain, and use clover hullers or fanning mills to harvest clean seed.

Adapting to distinct species The narrative systematically analyzes individual clovers, contrasting deep-rooted alfalfa in Western mountain valleys with alsike in damp northern fields and crimson clover in southern winter rotations.

Reclaiming neglected land It concludes by examining aggressive self-seeders like Japan, white, and sweet clover, showing how they bind loose soil on embankments and restore fertility to worn-out pastures.

The People

Thomas Shaw The author acts as a definitive guide, seeking to supply North American farmers with a clear, systematic reference on clover cultivation. Driven by a desire to bridge the gap between experimental station bulletins and practical field application, he uses rigorous observation to dispel common farming myths, such as the belief that seed straw must rot in fields before threshing.

Medium Red Clover The primary workhorse of the farm, this variety strives to establish itself in crop rotations across the Midwest and Western valleys. It struggles against extreme summer heat, severe bare-ground frosts, and crowding weeds, ultimately succeeding as a reliable two-cut crop for hay and soil nitrogen.

Alfalfa A vigorous, deep-rooting giant that seeks to expand across dairy regions and mountain river valleys. It faces constant threats from acidic subsoils, standing water, and winter ice, yet rewards the farmer with immense yields when given porous ground and proper bacterial conditions.

Alsike Clover A slender, pink-flowered survivor designed for cold, wet, or sandy northern lands where medium red fails. Though yielding coarser hay, its moisture tolerance and long-lived nature make it essential for renewing partial stands on low ground.

In Its Own Voice

"Clover seeds, like those of grasses, are buried most deeply in the light soils of the prairie so light that they sink, so as to make walking over them unusually tiresome when working on newly plowed land..."

This observation highlights the physical reality of western prairie soil conditions during early spring planting.

"In certain areas the judicious use of land plaster on the clover hastens the renovating process."

Here the author notes a cost-effective soil amendment technique that accelerates pasture renewal without excessive labor.

"A more beautiful sight is seldom seen than that of a vigorous crop of crimson clover in full bloom."

This vivid line reflects the author's visual appreciation for a lush, scarlet catch crop growing in early summer.

What It's Really About

Underneath its practical instructions on seed drills and hay cocks, the book argues for ecological stewardship through informed farm design. It challenges the extractive agricultural practices of the era, contending that natural biological processes—specifically nitrogen fixation and deep root aeration—can permanently renew exhausted soils far better than heavy manual labor or artificial quick fixes. The text continuously questions how farmers can work in harmony with regional climates, soil types, and specialized plant habits rather than forcing a single crop into unsuited environments. By framing clovers as versatile tools for weed suppression, pasture improvement, and erosion control, the work presents a cohesive vision of sustainable self-sufficiency, where careful species selection and timing guarantee long-term agricultural resilience.

Why Read It Today

Modern readers interested in sustainable agriculture, homesteading, or historical land management will find this volume surprisingly relevant. Reading it feels like standing in an early twentieth-century field alongside a patient, extraordinarily observant mentor who understands every nuance of the soil beneath his boots. The prose carries a clear, rhythmic authority that turns complex agronomic details into engaging instruction. While contemporary readers must navigate dated technical terms and historical farming machinery descriptions, the fundamental ecological insights remain remarkably sound. What stays with you is the author's deep respect for natural systems and his insistence that working with plant biology rather than against it is the true key to lasting farm prosperity.
